Avibrim Privacy Policy
Avibrim ("the app") is developed by ByteRealm ("we", "us"). Avibrim lets you create custom vibration patterns and assign them to your contacts, so you can tell who is calling without looking at your phone. This policy explains what information the app uses, what leaves your device, and the choices you have.
In short: your contacts, caller phone numbers and vibration assignments stay on your phone. We collect anonymous usage statistics and crash reports, tied to a random ID rather than to you, to keep the app working and improve it. We do not sell your data, show ads, or read your messages.
1. Information that stays on your device
- Contacts. Avibrim reads the names, phone numbers and photos in your contacts to show the list you assign patterns from. Your contacts are never uploaded.
- Incoming caller numbers. When a call comes in, Avibrim looks at the caller's number to choose the right vibration pattern. On Android 10 and newer, Android provides the number because you set Avibrim as your caller ID & spam app. The number is used only at that moment and is not stored or sent anywhere.
- Your assignments and patterns. The patterns you create and which pattern belongs to which phone number are saved in a database inside the app. They are deleted when you uninstall Avibrim.
- Exported patterns. If you export a pattern, it is saved to a file in the location you choose on your device.
2. Information we collect
To understand how the app is used, fix crashes and handle purchases, Avibrim sends the following to our analytics service (Zofeh, at api.zofeh.com). All of it is sent over an encrypted HTTPS connection.
| What | Details | Why |
|---|---|---|
| Random install ID | A random identifier created when the app is installed. It is not linked to your name, phone number, account or advertising ID. | To count installs and group the events below |
| Device and app information | Device model and manufacturer, Android version, language, time zone, screen resolution, app version and install date | Compatibility and troubleshooting |
| Usage events | Which screens and features are used (for example, opening the editor or saving a pattern), and how many contacts and patterns you have set up, as totals only. Never names or phone numbers. | To improve the app |
| Crash reports | Technical details about errors in the app | To find and fix bugs |
| Purchase information | If you buy the premium upgrade: product, order ID, purchase time and purchase token | To verify purchases and apply promotions |
| Install source | How the app was installed (the Google Play install referrer), such as a referral link | To understand which channels bring users and to apply referral offers |
| Push token | The token Google provides for sending notifications to this install | To send occasional app notifications |
3. Services provided by Google
- Google Play Billing processes purchases. Payment details are handled by Google; we never see your card or payment information.
- Firebase Cloud Messaging delivers push notifications.
- Google Play Install Referrer reports how the app was installed.
Google's handling of this information is described in the Google Privacy Policy.
4. Permissions and why the app needs them
| Permission | Why |
|---|---|
| Contacts | Show your contacts so you can assign patterns to them |
| Phone (call state) | Know when a call starts ringing, is answered or ends, so the vibration starts and stops at the right time |
| Caller ID & spam app role | On Android 10 and newer, this is how Android tells the app who is calling. Avibrim never blocks, rejects or silences calls. |
| Do Not Disturb access | Temporarily change the ringer mode so your custom vibration plays instead of the standard one, then restore it |
| Vibrate | Play your vibration patterns |
| Modify system settings | Adjust vibration settings on older Android versions |
| Storage | Export and import vibration patterns on older Android versions |
| Notifications | Show app notifications |
| Run at startup, prevent sleep | Keep custom vibrations working after the phone restarts and while a call is ringing |
| Internet | Send the information described in section 2 |
| Google Play Billing | Offer the premium upgrade |
5. What we do not do
- We do not sell, rent or trade your information.
- We do not show ads or use advertising IDs.
- We do not upload your contacts, call history or caller numbers.
- We do not read your SMS or other messages, record calls, or access your location.
6. Keeping and deleting your information
- Information on your device is removed when you uninstall Avibrim.
- Analytics information is tied only to the random install ID. We keep it only as long as needed to run and improve the app.
- To ask us to delete the information associated with your install, contact us at the address below.
7. Children
Avibrim is not directed at children under 13, and we do not knowingly collect information from children.
8. Changes to this policy
If we change this policy, we will update it on this page and change the effective date above. Significant changes will also be mentioned in the app's release notes.
