Privacy Policy – Unthink

Last updated: 3 October 2026

Unthink is made by Nico Lange, Schlehenstraße 29, 71540 Murrhardt, Germany ("we", "us"). Contact: hello@getunthink.app.

The short version

• What you write and do in Unthink stays on your phone. We never see it.
• One exception, and only if you switch it on: what you write to Bloom, the AI assistant, is sent to an AI service to write the reply. We keep no copy of it.
• No account, no ads, no tracking, no analytics.
• Apart from that we only receive what is technically needed to run subscriptions.

1. What stays on your phone

Unthink stores the following only in the app's storage on your device:

• the name you enter (optional) and your answers from the first-run questions
• which exercises you did and how you answered "Better?"
• your favorites and settings (haptics, help-line country, check-in time)
• messages and worries you park, and your saved "Fact vs. Story" cards
• your conversations with Bloom

Unless you use Bloom (section 2), none of this is sent to us or to anyone else, and we cannot read, analyse, share or restore it.

Deleting it: Settings → Delete everything removes all of it at once, including scheduled reminders. Deleting the app does the same.

Device backups: if you back up your phone (for example with iCloud Backup), the app's storage can be part of that backup like any other app's. That backup is between you and your backup provider; we have no access to it.

2. Bloom, the AI assistant

Bloom is a part of Unthink Premium that you can write to. Bloom is an AI, not a person and not a therapist. It is off until you switch it on: the first time you open Bloom, the app tells you what happens with your words and asks for your agreement. Bloom is only for people aged 18 or older.

What is sent when you use Bloom:

• the messages you write to Bloom in that conversation, and Bloom's replies so far
• the topic you picked and the time of day on your phone (the hour only)
• your first name if you entered one, your answers from the first-run questions (what your worry is about and when it shows up), and what you told Bloom about yourself and how it should talk to you
• in "Fact vs. Story", only when you tap "Ask Bloom for ideas": the fact and the story you wrote on that card
• the random app user ID from section 4, so the server can check your subscription

Nothing else in the app is sent: not your parked messages, not your Reality Check, not your patterns.

Who receives it:

• Anthropic (Anthropic, PBC, USA) provides the AI model that writes the reply. Under its terms for business customers, Anthropic does not use this data to train its models. It deletes what was sent and the replies within 30 days, unless it must keep them longer by law or to enforce its usage policy (for example, content flagged for abuse).
• Cloudflare (Cloudflare, Inc., USA) runs our small server that passes your message on to Anthropic and checks your subscription. The server does not store what you write or what Bloom answers. It only stores counters next to your random app user ID: how much of your monthly Bloom allowance is used. These contain no content.

We ourselves keep no copy of your conversations and cannot read them. They are saved on your phone only.

Sensitive information: what you write to Bloom can say something about your health. That is why Bloom only works with your explicit consent.

• Legal basis: your explicit consent (Art. 6 (1) (a) and Art. 9 (2) (a) GDPR).
• Withdrawing consent: switch Bloom off under Settings → Bloom at any time. From then on nothing is sent. This does not affect what was processed before.
• Transfer to the USA is based on the EU Standard Contractual Clauses in Anthropic's and Cloudflare's data processing agreements.
• Deleting: conversations on your phone are deleted with Settings → Delete everything or one by one in the list of conversations. Copies at Anthropic are deleted automatically as described above. The counters next to your app user ID are deleted automatically after 62 days at the latest. Beyond that we only keep monthly totals without any ID (for example how often Bloom was used overall).

Please keep in mind: if you paste someone else's messages, leave out names and phone numbers. Bloom is not for emergencies. If you are in danger, use Get help in the app or call your local emergency number.

3. Notifications

Reminders (the daily check-in and "parked" items) are scheduled locally on your phone. We do not run a push server and do not receive a notification token. The texts are neutral on purpose and never contain what you wrote. You can turn them off in the app or in your phone's settings at any time.

4. Subscriptions

Purchases are processed by Apple (App Store). We never receive your payment details.

To check whether a subscription is active we use RevenueCat (RevenueCat, Inc., USA) as our processor. RevenueCat receives: a random app user ID created on your device, the product you bought, purchase and renewal dates, the store country, and technical data such as your device type, OS version and IP address. It does not receive your name or anything you wrote in the app. If you use Bloom, our server also asks RevenueCat whether the subscription behind your random app user ID is active.

• Legal basis: performance of the contract (Art. 6 (1) (b) GDPR).
• Transfer to the USA is based on the EU Standard Contractual Clauses in RevenueCat's Data Processing Addendum.
• Storage: for as long as needed for billing and legal retention duties.

5. Crash reports

If the app crashes, a technical report (error message, device type, OS and app version) is sent to Sentry (Functional Software, Inc., USA) so we can fix the problem. The reports are stored in Sentry's EU region (Frankfurt, Germany). They contain no texts you entered, no name and no advertising ID. Legal basis: our legitimate interest in a stable app (Art. 6 (1) (f) GDPR). Reports are deleted automatically after 90 days at the latest.

6. Help lines

When you tap a help-line number, your phone's own phone or messaging app opens. We do not learn that you did this or whom you contacted.

7. What we do not do

No advertising, no tracking across apps or websites, no selling of data, no profiling, no analytics SDKs. Your words are never used to train AI models.

8. Children

Unthink is made for adults. It is not intended for anyone under 16. Bloom is only for people aged 18 or older.

9. Your rights (GDPR)

You have the right to access, rectification, erasure, restriction, data portability and to object, and you can withdraw a consent at any time. Since your content exists only on your phone, you exercise most of these directly in the app. For subscription data or questions about Bloom write to hello@getunthink.app. You can also complain to a data protection authority, for example the one responsible for us: Der Landesbeauftragte für den Datenschutz und die Informationsfreiheit Baden-Württemberg, Stuttgart (https://www.baden-wuerttemberg.datenschutz.de).

10. This website

This website (getunthink.app) only shows information and these legal pages. It uses no cookies, no analytics and no tracking. It is hosted by Netlify (Netlify, Inc., USA). When you open a page, Netlify's servers log your IP address, the time and the requested page to keep the service secure and running; these logs are deleted after 30 days. Legal basis: our legitimate interest in a secure website (Art. 6 (1) (f) GDPR). Transfer to the USA is based on the EU Standard Contractual Clauses in Netlify's Data Processing Agreement.

If you e-mail us, we use your address and message only to answer you and delete the conversation when it is no longer needed.

11. Changes

If the app starts handling data differently, this policy changes first, and the date above with it. Material changes are announced in the app.
