Fiden Terms of Use

Effective date: 25 August 2026

These Terms of Use (the "Terms") are a legal agreement between you and Pink Elephant, Unipessoal Lda ("Fiden," "we," "us" or "our"), governing your access to and use of the Fiden web application at fiden.app and the tools we make available there (together, the "Service"). Please read them carefully, particularly Section 4, before you start using Fiden.

The key points

  • Fiden is a relationship self-reflection tool. It is not therapy, counselling or couples therapy, it does not provide medical, psychological or legal advice, and it is not an emergency or crisis service.
  • You must be 18 or older to use Fiden.
  • AI-generated content can be wrong. Always use your own judgment, and speak to a qualified professional before making an important decision about your relationship or your health.
  • Fiden works with what you tell it about your partner and other people. You are responsible for what you choose to share. See Section 9.
  • Paid subscriptions renew automatically unless you cancel. See Section 6.
  • These Terms limit our liability and explain how disputes are handled. See Sections 14, 15 and 18.

1. Acceptance of these Terms

By creating an account, or by using any part of the Service, you agree to be bound by these Terms. If you do not agree to them, you must not use the Service. Our separate Privacy Notice explains how we collect and use personal data, our Cookie Policy explains our use of cookies on fiden.app, and our Refund Policy explains cancellations and refunds. All three form part of your agreement with us.

2. Eligibility

You must be at least 18 years old to use Fiden. By creating an account or otherwise using the Service, you confirm that you meet this requirement. The Service is not directed at, and must not be used by, children.

3. The Service

Fiden is a relationship-support application that helps you think about your relationship. It guides you through structured sessions with an AI companion, builds a private picture of your relationship across eight areas of life together, suggests questions you may want to bring to your partner, and keeps track of what you have already worked through.

Fiden runs in a web browser at fiden.app. It is not distributed through the Apple App Store or Google Play, and there is nothing to download or install.

Some parts of the Service, including a free relationship quiz, are available without creating an account. Section 10 sets out additional terms specific to them.

We may add, change or remove features of the Service at any time, and we may suspend or discontinue the Service, in whole or in part, giving reasonable notice where practicable.

4. Important disclaimer: what Fiden is not

Fiden is a self-reflection and relationship-support tool. It is not therapy, counselling, couples therapy, coaching by a licensed professional, or any form of medical or mental-health treatment. It is not a medical device, and it does not provide medical, psychological or legal advice, diagnosis or treatment. Nothing in the Service creates a therapist-client, counsellor-client, doctor-patient or lawyer-client relationship, and nothing in it replaces the advice of a qualified professional.

Although Fiden draws on ideas from established therapeutic approaches, the questions it asks, the observations it offers, the picture it builds of your relationship and any suggestion it makes are illustrative and educational only. They are generated automatically from what you have told it, they do not reflect the judgment of a qualified professional, and they must not be used as the sole basis for any important decision.

Decisions about your relationship and your life are yours alone. This includes any decision to stay in a relationship, to separate or divorce, to raise a subject with your partner, or to start, change or stop any treatment or medication. If your situation is serious, please involve a qualified professional: a therapist or counsellor, a doctor, or a lawyer.

Fiden is not an emergency or crisis service, and is not designed or equipped to detect or respond to an emergency. Its automated safety features do not include detection of a mental-health crisis, of thoughts of self-harm, or of abuse, coercion or domestic violence. If you are in crisis, or believe that you or someone else may be in danger, contact your local emergency services immediately, or an appropriate crisis or domestic-abuse helpline. Do not rely on Fiden in an emergency.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, YOUR USE OF THE SERVICE, AND ANY RELIANCE YOU PLACE ON INFORMATION OR CONTENT PROVIDED THROUGH IT, IS AT YOUR OWN RISK.

5. Your account

To use most features of Fiden, you need an account. You create one by giving us your email address, and you sign in with a one-time code or a one-time sign-in link that we send to that address.

You agree to provide an accurate email address that belongs to you, and to keep access to that email account secure. You are responsible for all activity that occurs under your account, and you should not share your sign-in codes or links with anyone, including your partner. Let us know at [email protected] if you suspect unauthorized use of your account.

You can ask us to delete your account at any time by writing to [email protected]. We will action your request without undue delay. Deleting your account removes your access to the Service. Our Privacy Notice explains what happens to your data when you do.

6. Subscriptions and payment

Most features of Fiden require a paid subscription. The subscription periods available, the price of each, and any discount are shown to you before you subscribe. Prices are in US dollars unless we show otherwise, and include applicable taxes where we are required to charge them.

Unless stated otherwise at the point of purchase, subscriptions renew automatically at the end of each billing period, at the price shown to you for renewals, until you cancel.

You can cancel at any time by writing to [email protected]. We will confirm your cancellation by email. Cancellation takes effect at the end of the current billing period, and you keep access until then.

We offer a 30-day money-back guarantee. If you are not satisfied, write to [email protected] within 30 days of a charge, including a renewal charge, and we will refund it in full. Our Refund Policy explains how this works and forms part of your agreement with us. Outside the guarantee, we do not provide refunds for the unused portion of a billing period, except where required by law.

Payments are processed by our payment provider, Stripe. We do not receive or store your full payment card details.

If you are a consumer in the EU, you may have a statutory right to withdraw from a purchase within 14 days. Because the Service is digital content supplied immediately, you lose this right once we begin performance with your express consent and your acknowledgment that you thereby lose the right of withdrawal, to the extent permitted by applicable law. Our money-back guarantee above applies regardless.

7. Acceptable use

When using the Service, you agree not to:

  • use the Service for any unlawful purpose, or in a way that infringes anyone else's rights;
  • impersonate any person, or misrepresent your affiliation with any person or entity;
  • create an account on behalf of another person, or use the Service to submit content purporting to come from another identifiable individual;
  • use the Service to monitor, profile, manipulate, pressure or build a case against another person;
  • attempt to gain unauthorized access to the Service, other users' accounts, or our systems;
  • interfere with or disrupt the Service, including through malware, scraping, or excessive automated requests;
  • reverse engineer, decompile, or attempt to extract the source code of the Service, except to the extent applicable law permits it despite this restriction;
  • attempt to extract, copy or reuse the prompts, models, knowledge base or other underlying materials of the Service, or use the Service to build a competing product; or
  • use the Service to harass, abuse, or harm another person.

We may investigate and take appropriate action, including suspending or terminating your account, if we reasonably believe you have violated these Terms.

8. AI-generated content

Fiden's sessions and related features use third-party AI technology to generate questions, observations and summaries based on the information you provide. AI-generated content may be inaccurate, incomplete, or inappropriate for your situation, and does not reflect the judgment of a qualified professional. In particular, any conclusion Fiden appears to draw about you, your partner or your relationship is a guess based on limited information, not a finding of fact.

You should use your own judgment, and consult a qualified professional, before acting on anything Fiden tells you. Section 4 applies fully to AI-generated content.

9. Information about your partner and other people

Fiden works by asking you about your relationship, so you will naturally tell it things about your partner and sometimes about other people, such as family members or friends. You decide what to share.

You are responsible for the information about other people that you submit, and you confirm that you are entitled to share it and that sharing it does not infringe anyone else's rights or violate applicable law. Please share only what you are comfortable sharing, and consider that the other person has not agreed to these Terms and may not know that you use Fiden.

We use this information only to provide the Service to you, as described in our Privacy Notice. We do not contact your partner or anyone else you mention unless you ask us to, and we do not pass your session content to them. If we later offer a feature that involves your partner directly, we will explain clearly what is shared before anything is shared.

10. The free quiz and other tools available without an account

The relationship quiz and any other tools we make available on fiden.app without an account provide illustrative and educational information only. They are not an assessment, a diagnosis, or professional advice of any kind, and they are subject to the disclaimer in Section 4. Any result they show, including any picture of how your relationship is doing across different areas, is generated automatically from the answers you give and reflects nothing more than those answers.

11. Your content

You may submit content to the Service, such as your answers in the quiz, what you write during a session, and any notes or feedback you send us ("Your Content"). You retain ownership of Your Content.

By submitting it, you give us a limited license to host, store and process Your Content solely to provide and improve the Service to you, consistent with our Privacy Notice. Providing the Service includes sending Your Content to the third-party AI providers we use to generate responses. We do not claim ownership of Your Content, and we do not use it to train third-party AI models beyond what our Privacy Notice describes.

You are responsible for Your Content, and you confirm that submitting it does not infringe anyone else's rights or violate applicable law.

12. Our intellectual property

The Service, including its software, design, text, and the Fiden name and logo, is owned by us or our licensors and is protected by intellectual property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for your personal, non-commercial use, subject to these Terms. Except for this license, we do not grant you any rights in the Service, and you must not copy, modify, distribute, or create derivative works from it without our permission.

13. Third-party services and links

The Service relies on and may link to third-party services, such as our AI providers, our payment provider, our email provider and the analytics providers described in our Privacy Notice. We are not responsible for the content, accuracy, or practices of third-party services, and your use of them is subject to their own terms and privacy policies.

14. Disclaimer of warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT, EXCEPT WHERE SUCH WARRANTIES CANNOT BE EXCLUDED UNDER APPLICABLE LAW. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE OR SECURE, OR THAT ANY QUESTION, OBSERVATION, SUMMARY OR OTHER AI-GENERATED CONTENT WILL BE ACCURATE OR SUITABLE FOR YOUR CIRCUMSTANCES.

Nothing in this Section limits any statutory right you have as a consumer that cannot lawfully be excluded or limited.

15. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, ARISING FROM OR RELATING TO YOUR USE OF THE SERVICE. THIS INCLUDES ANY LOSS OR HARM RELATING TO YOUR RELATIONSHIP, YOUR FAMILY OR YOUR EMOTIONAL WELLBEING. OUR TOTAL LIABILITY FOR ANY CLAIM ARISING FROM OR RELATING TO THE SERVICE WILL NOT EXCEED THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM AROSE, OR US$100 IF YOU HAVE NOT PAID US ANYTHING.

Nothing in these Terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be excluded or limited under applicable law, including the mandatory rights of consumers under the law of your country of habitual residence.

16. Indemnification

You agree to indemnify and hold us harmless from any claim, loss or expense, including reasonable legal fees, arising from your violation of these Terms, your misuse of the Service, or Your Content, except to the extent caused by our own breach of these Terms or applicable law.

17. Termination

You may stop using the Service and delete your account at any time. We may suspend or terminate your access to the Service if you breach these Terms, if we reasonably believe your use poses a risk to us, other users, or third parties, or if we discontinue the Service, in each case giving notice where reasonably practicable. Sections that by their nature should survive termination, including Sections 4, 9, 11, 12, 14, 15, 16 and 18, will continue to apply.

18. Governing law and disputes

These Terms are governed by the laws of Portugal. If you are a consumer habitually resident in the EU, this choice of law does not deprive you of the protection of any mandatory consumer-protection provisions of the law of your country of residence, and you may bring proceedings before the courts of your own country of residence as well as the courts of the district of Lisbon, Portugal, which the parties otherwise submit to on a non-exclusive basis.

We encourage you to contact us first at [email protected] to try to resolve any complaint informally. The European Commission's Online Dispute Resolution platform was discontinued in July 2025. If you are an EU consumer, you may still be able to refer an unresolved dispute to the competent out-of-court consumer dispute resolution body in your country of residence.

19. Changes to these Terms

We may update these Terms from time to time. If we make a material change, we will notify you through the app or by other reasonable means before the change takes effect. Continuing to use the Service after a change takes effect means you accept the updated Terms. If you do not agree, you should stop using the Service and may delete your account.

20. General provisions

If any provision of these Terms is found unenforceable, the rest will remain in effect. Our failure to enforce a provision is not a waiver of our right to do so later. We are not liable for any delay or failure to perform caused by circumstances beyond our reasonable control. You may not assign these Terms without our consent. We may assign them in connection with a merger, acquisition, or sale of assets, consistent with our Privacy Notice. These Terms, together with our Privacy Notice, Cookie Policy and Refund Policy, are the entire agreement between you and us regarding the Service.

21. Contact us
