Privacy Policy

Flumi — Last updated: 4 Nov 2026

Flumi is built so that everything you enter stays on your iPhone. The app does not collect any personal data, and we, STG Ventures GmbH, never see what you store in it.

No data collection

  • no server connection
  • no account, no sign-up
  • no tracking, no analytics
  • no advertising
  • no cloud sync
  • no sharing with third parties

What the app stores on your iPhone

Flumi only stores the content you create yourself: your first name (optional), your subjects with their name, symbol and color, your tests with date and topics, your study plan, your completed study sessions, and settings such as study days, reminder time, timer length and music. This data stays exclusively on your iPhone and is neither seen nor transmitted by us.

Notifications

Flumi uses local notifications for your daily study reminder and to let you know when a focus session is done. They are scheduled on your device; no notification service of ours is involved. You can turn them off at any time in the app or in your iPhone Settings.

Music

The lo-fi music is built into the app and plays offline; no streaming service is involved. The music credits contain links to the artists' websites and licenses. If you open one, it opens in your browser, and that website's own privacy policy applies.

Purchases and subscriptions

Flumi Plus is offered as an in-app subscription handled by Apple. Payments, subscription management and receipts are processed by Apple through your App Store account; we do not receive any payment data. Apple's privacy terms apply.

Backups

If you have iPhone backups turned on (for example iCloud Backup), your Flumi data may be included in them. These backups are managed by Apple under your Apple Account; we have no access to them.

Children and teenagers

Flumi is made for students, including teenagers. Because the app does not collect any personal data, no data of children or teenagers reaches us either.

Your control

You can change or remove your name, subjects and tests in the app at any time. Deleting the app removes all of its data from your iPhone permanently.

Changes to this policy

If this policy changes, we will update this page and the date above.
