BrainBunBrainBun Privacy Policy
Last updated: 14 November 2026
BrainBun (“the app”) helps you watch fewer short-form videos. This policy explains what the app reads, what it keeps, and what leaves your phone. Contact: support@brainbun.app.
What the app reads on your phone
BrainBun uses Android’s Accessibility Service to notice when a short video (Reels, Shorts, TikTok, Facebook Reels, Snapchat Spotlight) is on screen in Instagram, YouTube, TikTok, Facebook or Snapchat. It reads the screen layout and visible text of those five apps only, and only to decide whether a short video is showing and whether it is an ad.
- Everything it reads is processed in memory on your phone and thrown away immediately.
- It never stores or sends captions, usernames, comments, messages or any other screen content.
- It never taps, types or acts for you.
- It does not look at any other app.
You agree to this on an in-app screen before Accessibility is turned on, and you can turn it off at any time in Android Settings → Accessibility.
What is stored on your phone
For each counted video: which app and when. From that the app builds daily totals, streaks and your settings (daily limit, schedules). This stays on your phone.
What is sent to our servers
Only if you sign in with Google (needed for buddies and battles):
| Data | Why |
|---|---|
| Your first name and profile photo link (from your Google account) | so your buddies see who you are |
| Your email address, held by our sign-in provider | to sign you in |
| Your total number of reels per day (one number per day, no app breakdown) | daily battles |
| Your buddy links and invite codes | buddies |
| A push notification token and your time-zone offset | “buddy joined” and daily result notifications |
Nothing from your screen is ever sent. No location, contacts or browsing data are collected.
Service providers
We use trusted service providers to run the app: for data storage and server functions, for Google sign-in, and for delivering push notifications. They process data only on our behalf and only for those purposes.
Ads and selling data
BrainBun has no ads and no ad SDKs. We never sell or rent your data.
Keeping and deleting your data
Your data is kept while you have an account. In the app, Account → Delete account removes your profile, daily totals, buddy links, invites and push tokens from our servers. You can also ask for deletion without the app at https://brainbun.app/delete or by emailing support@brainbun.app; we delete within 30 days. Uninstalling the app deletes everything stored on your phone.
Security
Data is encrypted in transit (HTTPS). Access to our servers is limited to the developer.
Children
BrainBun is not meant for children under 13 and we do not knowingly collect their data.
Changes
If this policy changes we will update the date above and, for important changes, tell you in the app.
