Terms of Use

Relationship Detective · Last updated: 2026-09-02

1. Provider and scope

The app “Relationship Detective” is provided by Kevin Pfistner, Amtfeldstr. 27, 76316 Malsch, Germany (e-mail: kevin.pfistner@web.de). These terms govern the use of the app and the analysis service. Purchases of bottle caps are additionally subject to the terms of the app store (Google Play or Apple App Store) through which the purchase is made.

2. What the app does

The app analyses a chat history that you provide and produces a report: measurable patterns, notable passages with evidence, possible explanations with an indication of how well they are supported, what cannot be derived from the chat, and suggestions for you. The report is produced by an AI language model.

Limits of the service: An AI report may contain errors, misread context or miss something important. It describes behaviour in the chat, not the feelings or motives of the other person, and it is not psychological, medical or legal advice. You confirm this nature of the service separately in the app before an analysis starts.

3. Requirements and rules of use

• You are at least 18 years old.
• You upload only conversations you took part in yourself. Other people's chats, group chats without your participation, or content you have no rights to are excluded.
• You use the analysis solely for your own reflection. You do not use it to confront, expose, monitor or pressure the other person, and you do not publish reports relating to identifiable people.
• You do not interfere with the service (for example through automated requests or by circumventing rate limits or payment).

In case of violations we may exclude individual keys from the service.

4. Bottle caps (balance)

• Analyses cost bottle caps. The cost of each version is shown in the app. The first bottle cap per installation is a gift and cannot be transferred.
• You buy bottle caps as consumables through Google Play or the Apple App Store. The binding price in your local currency including taxes is shown by the store before purchase.
• Purchased bottle caps do not expire. They cannot be paid out in money or transferred to other people – but they can be moved to another device of your own (see below).
• Your balance is tied to your wallet key, not to an account. The key is stored on your device. Anyone who knows the key can use the balance; treat it like a password. If you delete the app or switch devices without saving the key or transferring the balance first, the balance is no longer reachable. In that case e-mail us with your order number from the store and we will check whether it can be restored.
• If a paid analysis cannot be delivered (technical error, you cancel before the result, a crisis notice is shown instead of an analysis), the bottle caps spent are refunded to your balance automatically. Once an analysis has been delivered, the bottle caps are used up.

5. Withdrawal and start of the service

The purchase of bottle caps is handled by the respective store as your contracting party; the store informs you about any right of withdrawal at the time of purchase. The analysis service begins as soon as you start an analysis; you expressly agree that we begin performance immediately and acknowledge that bottle caps redeemed for a delivered analysis cannot be returned.

6. Availability, changes, updates

We aim for continuous availability but cannot guarantee it – the service depends on the providers of the AI models and hosting. During incidents we may temporarily suspend purchases or analyses; your balance is not affected. We provide the updates needed to keep the app in conformity for as long as you can reasonably expect; please install them promptly. We may develop features further or change them with reasonable notice.

7. Warranty and liability

The statutory warranty rights for digital products apply to the app and the analysis service. We are liable without limitation for intent and gross negligence and for injury to life, body or health. In cases of slight negligence we are liable only for breach of essential contractual obligations and limited to the foreseeable damage typical for this kind of contract. Liability under product liability law remains unaffected. Decisions you take on the basis of a report are your own responsibility.

8. Rights to content

Your chats and reports remain your content; we acquire no rights to them beyond processing them for your analysis. The app, its texts, graphics and characters are protected by copyright; third-party licences are listed in the app under “Licences”.

9. Privacy

How we handle data is described in the Privacy Policy.

10. Changes to these terms

We may change these terms with effect for the future where there is a valid reason (for example a change in the law or new features). We announce material changes in the app; the changed terms apply to analyses you start afterwards.

11. Final provisions

The law of the Federal Republic of Germany applies. If you are a consumer habitually resident in another country, the mandatory consumer protection rules of that country remain unaffected. We are neither obliged nor willing to take part in dispute resolution proceedings before a consumer arbitration board. Should any provision be invalid, the remainder stays in force.
