Gomo: Privacy Policy
Last updated: 4 November 2026
Gomo ("the app") is made by Bui Dinh Dan ("we", "us"). This policy explains what information the app uses, why, and the choices you have. It covers the iOS and Android apps.
Summary
- No accounts and no sign-in. We never ask for your name, email, contacts, photos, microphone, camera or location.
- Your settings and meditation log are saved only on your device.
- The app shows no ads and contains no analytics SDK.
- When you're online, the app tells our presence server that someone is sitting in a sanctuary, so others see an anonymous silhouette.
- We do not sell your information.
Data Collection & Analytics
Stored on your device
Your chosen sanctuary, language, sound mix, breathing pattern, visual mode, reminder choice and your private meditation log (minutes, sits and streak days) are stored only on your device. They are never sent to us. Deleting the app deletes them.
Shared sanctuaries (online)
When you sit in a sanctuary while online, the app connects over an encrypted connection (TLS) to our presence server (wss://gomo.buidan.com/ws). The server receives:
- A random identifier created when you install the app. It is not linked to you, your device or any account, and is used only to avoid counting you twice when you reconnect.
- Which sanctuary you are sitting in, so you are given a cushion in that room.
- Offerings you choose to make (incense, bell, lotus candle, lantern), which are shown silently at your cushion to others in the room.
- Your IP address, which is part of any internet connection. It may appear briefly in server logs for security and troubleshooting.
Others in the room see only an anonymous silhouette and the number of people present. The server keeps nothing after you leave. There is no chat, voice or video. Offline, nothing is sent.
Reminders
If you turn on reminders, the app schedules local notifications on your device before the 05:00 and 21:30 group sits. They are created on your phone; nothing is sent from a server.
Advertising and analytics
The app shows no ads and does not use Google Analytics, Firebase Analytics or any other analytics or tracking SDK.
Third-Party SDK Disclosures
The app includes no third-party advertising, analytics or tracking SDKs.
| Service | What it receives | Why | Policy |
|---|---|---|---|
| Apple App Store / Google Play | Download and purchase records (sanctuary unlocks, offerings, Sanctuary Pass) handled by the store. We never see your payment details. | To distribute the app and process optional purchases. | Apple, Google |
Children's Privacy (COPPA)
The app is not directed at children under 13, and we do not knowingly collect personal information from children under 13, in line with the U.S. Children's Online Privacy Protection Act (COPPA) and similar laws. If you are a parent or guardian and believe your child has provided personal information through the app, email [email protected] and we will delete it.
Account & Data Deletion
The app has no accounts, so there is no account to delete. To delete your data, uninstall the app; this removes everything it stored. The presence server keeps no data after you leave a sanctuary. Subscriptions are managed and cancelled in your App Store or Google Play account.
Security
Information sent by the app travels over encrypted connections (TLS).
Changes
If this policy changes, we will update this page and the date at the top.
