Säckli

Privacy

Last updated: 17 October 2026

In short: Säckli has no account, no ads and no analytics. Camera and sound are processed on your iPhone and stay there. The app connects to the internet only when you send a round yourself.

What the app processes on your iPhone

This data stays in the app on your iPhone. When you delete the app, it is gone. It may be included in iPhone or iCloud backups, as with other apps.

When you send a round

Only when you start it yourself (Settings › Recordings) does the app pack the chosen rounds, one file each. Each file contains:

Uploading: the files go encrypted (HTTPS) to storage at Cloudflare (Cloudflare R2, located in the European Union). Cloudflare technically sees your IP address; we do not store it. Uploaded rounds are deleted from that storage after 180 days at the latest; what we need for the recognition is then kept only by us.

Sharing as a file: instead, you can send the rounds through the iOS share sheet (email, AirDrop, WhatsApp, ...); that service's own terms apply to it.

We use sent rounds only to improve bag recognition, including training the recognition models. We do not pass them on or publish them. We delete them on request.

The videos show the players and have sound. Ask the people in the picture before you send.

Beta through TestFlight

During the beta, Säckli is distributed through Apple's TestFlight. Apple shares with us your name and email address if we invited you by email, crash reports, feedback you send in TestFlight, and technical details such as the iPhone model and iOS version. Apple's TestFlight privacy notice applies to this.

What there is not

Possible optional features later

Later there may be, for example, anonymous usage statistics or other online features. Such features would be optional and off until you turn them on. We will update this policy before such a feature comes to the app.

Your rights

You can ask what data you sent us and have it deleted. Write to feedback@saeckli.ch.
