Privacy policy
Last updated 14 October 2026
In short
- DelFair has no account, no ads and no tracking.
- What you enter in the app is stored only on your phone. We have no copy.
- When you scan on the phone, the photo stays on the phone.
- When you use AI scan (Pro), the photo goes through our server to Anthropic, which reads the text. We don’t store the photo.
- Exchange rates come from Frankfurter. Only the currency codes are sent.
Who is responsible
DelFair is made by IDEA Studios, run by Isak Denstadli, who is the data controller for the processing described here.

What is stored on your phone
To work, the app stores the following on your phone:
- the names you add and their colours
- receipts: shop, items, prices and who got what
- saved groups, trips and history
- the payer’s mobile number, if you enter it
- your settings, such as language and currency
None of this is sent to us or anyone else. You can edit and delete it in the app. “Clear history” in Settings deletes the history, and everything is deleted when you uninstall the app.
Camera and photos
The app asks for access to the camera and your photos only so you can take or pick a photo of a receipt. The photo is kept in memory while you split and is not saved when the app closes.
Please avoid photographing card or account numbers.
Scanning
On the phone (Google ML Kit)
The phone reads the text itself, and the photo and the text stay on the phone. Google ML Kit sends technical information to Google for diagnostics and usage statistics: phone model, operating system version, app version, a random installation ID, how long the reading took, and any error codes. Google encrypts this and does not share it with third parties.
AI scan (DelFair Pro)
When you choose AI scan:
- The app makes the photo smaller and sends it encrypted to our server.
- The server passes the photo to Anthropic, the maker of Claude. Claude reads the receipt and returns the text.
- The server sends the text to the app and forgets the photo. We do not store or log the photo or the text.
The server uses your IP address briefly to prevent abuse. It is not stored.
Anthropic does not use the photo to train its models and deletes it within 30 days. If a request is flagged for violating Anthropic’s usage policy, Anthropic may keep it for up to 2 years. See Anthropic’s privacy policy.
Exchange rates (DelFair Pro)
If a receipt is in another currency, the app can fetch today’s rate from Frankfurter, a free service that publishes the European Central Bank’s reference rates. The app sends only the two currency codes, for example EUR and NOK. Like any online service, Frankfurter sees your IP address.
App updates
The app can check for and download updates from Expo (EAS Update). Expo then receives technical information such as your IP address, the app version, whether the phone is an iPhone or Android, and a random installation ID.
Buying DelFair Pro
Purchases and subscriptions are handled by Apple (App Store) or Google (Google Play). We never receive your card details. The app only learns whether you have an active subscription, so Pro can be unlocked. Apple’s and Google’s own privacy policies apply to the purchase itself.
Sharing
The app never shares anything by itself. When you tap “Share”, you choose where the settlement goes.
Who receives data
| Who | What they receive | When |
|---|---|---|
| Vercel Inc. (USA), which runs our server | The photo in transit through the server, and your IP address | AI scan |
| Anthropic PBC (USA) | The photo of the receipt | AI scan |
| Google (ML Kit) | Technical information about the phone and app, not the photo | Scanning on the phone |
| Frankfurter | Currency codes and your IP address | When the app fetches a rate |
| Expo / 650 Industries Inc. (USA) | Technical information and your IP address | When the app checks for updates |
| Apple and Google | The purchase and subscription | When you buy Pro |
Some of these are based in the USA, outside the EEA. Transfers rely on the European Commission’s Standard Contractual Clauses or the EU–US Data Privacy Framework.
Legal basis
- AI scan and exchange rates: to provide the service you ask for (GDPR Article 6(1)(b)).
- Technical information on the server, for updates and on the website: our legitimate interest in running a service that works and is secure (Article 6(1)(f)).
How long data is kept
- On your phone: until you delete it or uninstall the app.
- On our server: nothing is stored.
- At Anthropic: deleted within 30 days, or up to 2 years if a request is flagged.
- At Vercel, Expo and Google: according to their own routines for technical logs.
Your rights
You have the right to access, rectification, erasure, restriction, data portability and to object to processing. Since we don’t store data about you, you control most of it yourself in the app. Contact support@ideastudios.no with any questions.
You can complain to the Norwegian Data Protection Authority (Datatilsynet) or to the supervisory authority where you live.
