Sereneo Terms of Service
Version 1.1 — Effective Date: 19 July 2026
1. Parties, Acceptance and Formation of Contract
1.1. These Terms of Service (the “Terms”) constitute a legally binding agreement between you and Planviah Helgesen, a sole proprietorship (enkeltpersonforetak) organised under the laws of Norway, registered under organisation number 935 477 549, with registered address at Kringsjåveien 19, 5162 Laksevåg, Norway (the “Provider”, “we”, “us”), governing your access to and use of the Sereneo mobile application for iOS and the associated backend services (together, the “Service”).
1.2. By creating an account, or by accessing or using the Service in any manner, you accept these Terms and agree to be bound by them. If you do not agree to these Terms, you must not use the Service. During onboarding you will be asked to confirm your acceptance of these Terms and your acknowledgement of the Sereneo Privacy Policy (the “Privacy Policy”), available at https://sereneo.app/privacy.
1.3. The contract between you and the Provider is formed upon the creation of your account. The contract is concluded in English. These Terms, together with the Privacy Policy, constitute the entire agreement between you and the Provider with respect to the Service and supersede all prior understandings with respect to the same subject matter.
1.4. If any provision of these Terms conflicts with a provision of the Privacy Policy in a matter concerning the processing of personal data, the Privacy Policy prevails.
2. Definitions
2.1. In these Terms, the following expressions have the following meanings:
“Account” means the personal user account created by you for the use of the Service.
“AI Features” means the optional artificial-intelligence functions of the Service described in Section 8.
“Apple” means Apple Inc. and its subsidiaries.
“Service” means the Sereneo mobile application for iOS, the backend services with which it communicates, and any documentation, updates and new features made available by the Provider from time to time, unless accompanied by separate terms.
“User Content” means all content created, entered or uploaded by you within the Service, including journal entries, notes, mood check-ins, stress events, tags and preferences.
3. Eligibility
3.1. You may use the Service only if: (a) you are at least sixteen (16) years of age; (b) you have the legal capacity to enter into a binding contract under the law applicable to you; and (c) you are not prohibited from using the Service under any applicable law or regulation.
3.2. By using the Service you represent and warrant that the conditions in Section 3.1 are satisfied. The Provider may suspend or terminate any Account in respect of which it has reasonable grounds to believe that these conditions are not satisfied.
4. Description of the Service
4.1. Sereneo is a personal mental-wellness journaling application. The Service enables you to write private journal entries, to record mood check-ins and stress events, and, subject to your separate and explicit consent, to receive AI-generated emotional insights concerning your journal entries. Data created in the application is stored locally on your device and synchronised with the Provider’s servers when a network connection is available.
4.2. The Service is a self-reflection tool. It is expressly not therapy, not a medical or clinical service, not a diagnostic tool, and not a crisis or emergency service. The provisions of Section 9 apply to all use of the Service.
5. Account Registration, Security and Termination by You
5.1. Registration may be effected by email address and password, or through Sign in with Apple or Google Sign-In. You undertake to provide accurate and current information upon registration and to keep such information up to date for the duration of the contract.
5.2. You are responsible for maintaining the confidentiality of your credentials and for all activity occurring under your Account, save to the extent such activity results from a failure of security attributable to the Provider. You undertake to notify the Provider without undue delay at help@planviah.com upon becoming aware of any unauthorised access to or use of your Account.
5.3. The Account is personal to you. You may not share, sell, lease, transfer or otherwise make the Account available to any other person, and you may maintain no more than one Account.
5.4. You may terminate the contract at any time, without notice period and without cause, by deleting your Account within the application (Profile → Delete Account). Deletion of the Account takes immediate, permanent and irreversible effect, and its consequences for your data are described in the Privacy Policy.
6. User Content; Licence; Responsibility
6.1. As between you and the Provider, you retain all right, title and interest in and to your User Content. Nothing in these Terms transfers any ownership of User Content to the Provider.
6.2. You grant the Provider a non-exclusive, non-transferable, non-sublicensable (save to the processors identified in the Privacy Policy, and solely for the purposes stated therein), royalty-free licence to store, encrypt, transmit, reproduce for backup purposes, and otherwise process your User Content solely to the extent necessary to operate, secure, maintain and provide the Service to you, in accordance with the Privacy Policy. This licence terminates upon deletion of the User Content concerned or of your Account, subject only to the limited backup retention period described in the Privacy Policy, during which residual encrypted copies are unintelligible and are deleted automatically.
6.3. For the avoidance of doubt, the Provider does not use User Content for advertising, does not disclose User Content to third parties save as stated in the Privacy Policy, and does not use User Content for the training of artificial-intelligence models.
6.4. You are solely responsible for your User Content. You represent and warrant that your User Content is lawful and that its creation and storage within the Service does not infringe the rights of any third party.
7. Acceptable Use
7.1. You undertake, in connection with the Service, not to:
(a) use the Service for any purpose that is unlawful or in breach of any applicable law or regulation;
(b) access or attempt to access the accounts of other users, or any systems or networks of the Provider, without authorisation;
(c) probe, scan or test the vulnerability of the Service, or breach or circumvent any security or authentication measure, except pursuant to a coordinated-disclosure process published by the Provider;
(d) interfere with or disrupt the operation of the Service, including by imposing an unreasonable load on its infrastructure, by automated bulk access, or by scraping;
(e) reverse-engineer, decompile or disassemble the application, except to the extent such restriction is prohibited by mandatory law;
(f) misuse the AI Features, including by attempting to extract system instructions, to generate content unrelated to your own journaling, or to circumvent processing limits;
(g) impersonate any person or entity, or misrepresent your affiliation with any person or entity; or
(h) resell, sublicense, rent, lease or otherwise commercially exploit the Service.
7.2. A breach of this Section 7 constitutes a material breach of these Terms and may result in suspension or termination pursuant to Section 13.
8. AI Features
8.1. The AI Features consist of automated emotional analyses of journal entries, generated by a machine-learning model operated by the Provider’s processor OpenAI, L.L.C., as further described in the Privacy Policy. The AI Features are optional, are disabled by default, and operate only where you have granted the corresponding explicit consent within the application. You may withdraw that consent at any time in the application’s settings, whereupon the AI Features cease to operate; withdrawal has no effect on the availability of the remainder of the Service.
8.2. All content generated by the AI Features is identified as AI-generated within the application.
8.3. Limitations of AI-generated content. You acknowledge that content generated by the AI Features is produced by statistical methods, that it may be inaccurate, incomplete, inapposite or misleading, and that it reflects patterns in language rather than knowledge or understanding of you. AI-generated content does not constitute, and must not be relied upon as, a diagnosis, assessment, measurement or evaluation of your mental state or of any other matter. AI-generated content is provided solely as a prompt for your own reflection.
8.4. The Provider may modify, suspend or discontinue the AI Features, in whole or in part, at any time, including where required by law or by the terms of the Provider’s processor. Section 12.2 applies to any such modification.
9. No Medical Advice; Mental-Wellness Disclaimer; Emergencies
9.1. The Service provides self-reflection and journaling functionality for general wellness purposes only. Neither the Service nor any content within it — including AI-generated content — constitutes medical, psychological, psychiatric or other professional advice, diagnosis or treatment, and no professional–patient relationship of any kind is created by your use of the Service.
9.2. The Service is not a substitute for the advice or care of a qualified physician, psychologist, psychotherapist or other health professional. You must not disregard professional advice, or delay seeking it, on account of any content within the Service.
9.3. The Service is not a crisis service, is not monitored by any person, and does not detect, monitor or respond to indications of crisis or self-harm. If you are in crisis, or are considering harming yourself or another person, do not use the Service to seek help. Contact your local emergency services immediately — in Norway, the emergency number 113 or the Mental Helse helpline 116 123; elsewhere in the European Union, the emergency number 112 — or an equivalent crisis service in your country.
9.4. To the extent you make decisions on the basis of content within the Service, you do so at your own responsibility, without prejudice to Section 15.3.
10. Fees; Future Subscriptions; Apple In-App Purchase
10.1. The Service is at present provided free of charge.
10.2. The Provider may in the future offer optional paid subscriptions unlocking additional functionality. If and when paid subscriptions are introduced, the following shall apply:
(a) the core journaling and logging functions of the Service shall remain available free of charge, and the export of your data shall never be conditioned upon a paid subscription;
(b) subscriptions shall be offered, billed and administered exclusively through Apple’s In-App Purchase mechanism on the App Store; the Provider shall not collect or store payment-card details, and all payment processing shall be carried out by Apple under Apple’s own terms;
(c) the price, billing period and any free-trial terms shall be displayed within the application and on the App Store before any purchase; unless cancelled in accordance with Apple’s procedures, subscriptions renew automatically and the payment method associated with your Apple account is charged in accordance with Apple’s renewal terms;
(d) subscriptions may be managed and cancelled at any time through the subscription settings of your Apple account; cancellation takes effect at the end of the then-current billing period;
(e) refunds in respect of purchases made through the App Store are administered by Apple under Apple’s refund policies, and the Provider is not able to issue such refunds itself; nothing in this Section limits any mandatory right you hold under applicable consumer-protection law, including any statutory right of withdrawal; and
(f) the Provider shall amend these Terms and notify you within the application before paid subscriptions are introduced.
11. Terms Required by Apple
11.1. These Terms are concluded between you and the Provider only, and not with Apple. Apple is not responsible for the application or its content.
11.2. The licence granted to you in respect of the application is limited to a non-transferable licence to use the application on Apple-branded products that you own or control, as permitted by the Usage Rules set out in the Apple Media Services Terms and Conditions, save that the application may be accessed and used by other accounts associated with you via Family Sharing or volume purchasing.
11.3. Apple has no obligation whatsoever to furnish any maintenance or support services with respect to the application. In the event of any failure of the application to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) paid by you for the application; to the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the application, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty are the responsibility of the Provider.
11.4. As between the Provider and Apple, the Provider, and not Apple, is responsible for addressing any claims by you or any third party relating to the application or your possession or use of it, including: (a) product-liability claims; (b) any claim that the application fails to conform to any applicable legal or regulatory requirement; and (c) claims arising under consumer protection, privacy or similar legislation.
11.5. In the event of any third-party claim that the application, or your possession and use of it, infringes that third party’s intellectual-property rights, the Provider, and not Apple, is responsible for the investigation, defence, settlement and discharge of such claim, to the extent required by these Terms.
11.6. You represent and warrant that: (a) you are not located in a country that is subject to a United States Government embargo or that has been designated by the United States Government as a “terrorist supporting” country; and (b) you are not listed on any United States Government list of prohibited or restricted parties.
11.7. Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms Apple will have the right, and will be deemed to have accepted the right, to enforce these Terms against you as a third-party beneficiary hereof.
11.8. You must comply with applicable third-party terms of agreement when using the application.
12. Availability; Modifications to the Service
12.1. The Provider shall make reasonable efforts to keep the Service available and to synchronise your data reliably, but does not warrant uninterrupted availability. The Service may be temporarily unavailable by reason of maintenance, updates, capacity constraints or events outside the Provider’s reasonable control. The application stores your data locally on your device and synchronises it when a connection is available, so that temporary unavailability of the backend does not prevent local use.
12.2. The Provider may modify the Service from time to time, including by adding, altering or removing functionality, where such modification is justified by a valid reason, including technical development, security, legal or regulatory requirements, or the discontinuation of third-party services on which the Service depends. Where a modification materially reduces the core functionality of the Service to your detriment, you will be informed within the application in advance where reasonably practicable, and you may terminate the contract with immediate effect pursuant to Section 5.4.
12.3. In the event the Provider decides to discontinue the Service in its entirety, the Provider shall give you reasonable advance notice within the application and shall afford you a reasonable opportunity to obtain a copy of your data before the Service is withdrawn.
13. Suspension and Termination by the Provider
13.1. The Provider may suspend or restrict your access to the Service, or terminate the contract, where: (a) you are in material breach of these Terms, including Section 7, and, where the breach is capable of remedy, you have failed to remedy it within a reasonable period after notice; (b) suspension or termination is required by law or by order of a competent authority; or (c) suspension is strictly necessary to protect the security or integrity of the Service or the data of other users, in which case the suspension shall be limited to what the protection requires.
13.2. Save where a breach is serious or where notice would defeat the purpose of the measure, the Provider shall give you notice and an opportunity to respond before terminating the contract under Section 13.1(a).
13.3. Termination of the contract, by either party and for whatever reason, does not affect your right to obtain a copy of your data prior to deletion, nor the treatment of your data as described in the Privacy Policy. Sections 6 (as regards the winding-down of the licence), 9, 14, 15, 16, 17 and 18 survive termination.
14. Warranties and Disclaimer
14.1. To the maximum extent permitted by applicable law, the Service is provided “as is” and “as available”, and the Provider makes no warranty or representation, whether express, implied or statutory, including any implied warranty of merchantability, fitness for a particular purpose, accuracy or non-infringement. In particular, and without limitation, the Provider does not warrant that the Service will be uninterrupted, timely, secure or error-free, nor that AI-generated content will be accurate, complete or reliable.
14.2. Nothing in Section 14.1 or elsewhere in these Terms excludes, limits or modifies any warranty, guarantee or right which applies to you by virtue of mandatory law — including Norwegian consumer-protection law and the consumer-protection law of the country of your habitual residence within the European Union or the European Economic Area — and which cannot lawfully be excluded, limited or modified by agreement.
15. Limitation of Liability
15.1. To the maximum extent permitted by applicable law, the Provider shall not be liable for: (a) indirect, incidental, special, consequential, exemplary or punitive damages; (b) loss of profits, revenue, business or goodwill; or (c) loss of data, save where such loss is caused by the Provider’s breach of these Terms or of applicable data-protection law; in each case whether arising in contract, tort (including negligence), statute or otherwise, and whether or not the Provider was advised of the possibility of such damages.
15.2. To the maximum extent permitted by applicable law, the aggregate liability of the Provider arising out of or in connection with the Service or these Terms shall not exceed the greater of: (a) the total amounts paid by you to the Provider for the Service during the twelve months preceding the event giving rise to liability; and (b) fifty euros (EUR 50).
15.3. Nothing in these Terms excludes or limits the Provider’s liability: (a) for damage caused by gross negligence or wilful misconduct; (b) for death or personal injury caused by its negligence; (c) under applicable data-protection law, including Article 82 GDPR; or (d) for any other matter in respect of which liability cannot be excluded or limited under mandatory law. If you are a consumer, you retain in full every right afforded to you by the mandatory consumer-protection law of your country of habitual residence, and Sections 15.1 and 15.2 apply only to the extent permitted by that law.
16. Indemnification
16.1. If your use of the Service in breach of these Terms or of applicable law gives rise to a claim, demand or proceeding by a third party against the Provider, you shall compensate the Provider for the reasonable costs, expenses and damages that the Provider incurs as a direct result thereof, to the extent attributable to your breach and provided that the Provider notifies you of the claim without undue delay and does not settle it without your reasonable involvement.
16.2. This Section 16 applies to consumers only to the extent permitted by the mandatory consumer-protection law applicable to them, and shall not be construed to impose on a consumer any liability beyond that arising under the general law.
17. Intellectual Property
17.1. The Service — including the application software, the backend software, and all designs, interfaces, graphics, text (other than User Content), trademarks and logos comprised therein — is the property of the Provider or its licensors and is protected by intellectual-property law. Except for the limited licence described in Section 11.2, no right, title or interest in the Service is granted or transferred to you, and all rights not expressly granted are reserved.
17.2. “Sereneo” and the associated logos are trademarks of the Provider. No use of these marks may be made without the Provider’s prior written consent.
17.3. If you provide the Provider with feedback, suggestions or ideas concerning the Service, you grant the Provider a perpetual, irrevocable, worldwide, royalty-free licence to use them for any purpose without obligation or compensation to you. Feedback within the meaning of this Section does not include, and the Provider does not solicit, any User Content.
18. Governing Law; Jurisdiction; Consumer Rights
18.1. These Terms, and any non-contractual obligations arising out of or in connection with them, are governed by the laws of Norway, without regard to its conflict-of-laws rules.
18.2. The parties agree that Hordaland tingrett (the Hordaland District Court, Bergen, Norway) shall be the agreed venue for disputes arising out of or in connection with these Terms or the Service.
18.3. Consumer carve-out. If you are a consumer, nothing in Sections 18.1 and 18.2 deprives you of: (a) the protection afforded by provisions of the law of your country of habitual residence that cannot be derogated from by agreement; or (b) your right to bring proceedings in, or to be sued only in, the courts designated by the mandatory jurisdictional rules applicable to consumers, including the courts of your country of domicile.
18.4. Consumers resident in Norway may seek assistance with out-of-court dispute resolution from the Norwegian Consumer Council (Forbrukerrådet, www.forbrukerradet.no). Complaints concerning the processing of personal data may be addressed to the supervisory authority identified in the Privacy Policy.
19. Amendments to these Terms
19.1. The Provider may amend these Terms where the amendment is justified by a valid reason, including changes in the Service, in the law, or in the requirements of third parties on which the Service depends. Every version of these Terms bears a version number and an effective date.
19.2. In the case of a material amendment, the Provider shall notify you within the application in advance and, where the amendment significantly affects your rights or concerns processing resting on your consent, shall request your acceptance of the amended Terms before they apply to you. If you do not accept a material amendment, you may terminate the contract pursuant to Section 5.4 before the amendment takes effect. Amendments that are not material take effect upon publication at the address stated in Section 20.5.
20. General Provisions
20.1. Severability. If any provision of these Terms is held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired, and the invalid provision shall be deemed replaced by a valid provision that most closely reflects its economic and legal purpose.
20.2. No waiver. No failure or delay by either party in exercising any right under these Terms shall operate as a waiver of that right, nor shall any single or partial exercise of any right preclude any further exercise of it.
20.3. Assignment. You may not assign or transfer these Terms or any rights or obligations under them without the Provider’s prior written consent. The Provider may assign these Terms in connection with a merger, acquisition, corporate reorganisation or sale of all or substantially all of its assets, and shall notify you of any such assignment; where the assignment materially affects your position, you may terminate the contract pursuant to Section 5.4.
20.4. Force majeure. Neither party shall be liable for any failure or delay in performance, other than payment obligations, to the extent caused by circumstances beyond its reasonable control, including natural disasters, acts of war or terrorism, labour disputes, governmental action, failures of public networks or utilities, and failures of third-party services that could not reasonably have been prevented; provided that the affected party takes reasonable steps to mitigate the effects.
20.5. Notices; publication. Notices from the Provider to you may be given within the application or to the email address associated with your Account. Notices from you to the Provider shall be sent to help@planviah.com or to the registered address stated in Section 1.1. The current version of these Terms is published at https://sereneo.app/terms and is accessible from within the application.
