Everflow

Privacy Policy

Effective 24 August 2026 · Everflow for iOS · Burning Bros Inc.

The short version

Everflow asks for one thing — your date of birth — and that date never leaves your phone. Every number the app and its widgets show is calculated on the device from that one date. There is no account, no sign-in, and no profile of you anywhere.

The app does send anonymous diagnostics (how the app is used, and a report when it crashes) so we can keep it working. Those reports carry no date of birth and nothing that identifies you.

1. Who we are

Everflow is published by Burning Bros Inc. ("we", "us"). For anything in this policy, write to burningbrosinc@gmail.com.

2. What stays on your device

The following is stored only in the app's own storage on your iPhone, plus the app group container the home-screen and Lock Screen widgets read from. It is never uploaded to us or to anyone else, and we cannot see it:

Deleting the app deletes all of it. Because we never receive it, there is nothing on our side to delete, export, or lose.

3. What the app does send

Everflow uses two Google Firebase services in App Store builds. Google acts as our processor: it handles this data on our instructions and not for its own advertising.

DataWhyServiceKept for
App usage events — app opened, screens viewed, session length — plus a pseudonymous app-instance identifier, device model, OS version, and the country inferred from your IP address To see which parts of the app people actually use, so we know what to improve Firebase Analytics Up to 14 months
Crash reports — stack trace, device model, OS version, app version, and an installation identifier To find and fix the bug that caused the crash Firebase Crashlytics Up to 90 days

Our legal basis under the GDPR is our legitimate interest in keeping the app functional and in understanding, at an aggregate level, how it is used (Art. 6(1)(f)). Nothing above is used to make decisions about you, and none of it is combined with data from other apps or websites.

4. What we never do

5. Content updates

The illustrations and messages Everflow shows ship inside the app. The app contains the ability to fetch an updated, signed content bundle from our hosting; when that is switched on, the request carries no personal data — no identifier, no birth date, nothing but a check for a newer bundle version.

6. Children

Everflow is not directed to children under 13 (or the equivalent minimum age in your country), and we do not knowingly collect personal information from them. A date of birth entered by anyone, of any age, stays on the device.

7. International transfers

The diagnostics described in section 3 are processed by Google on servers in the United States and other countries where Google operates, under Google's standard contractual clauses for Firebase customers.

8. Your rights

Depending on where you live, you may have the right to access, correct, delete, or object to the processing of your personal information, and to lodge a complaint with your data protection authority.

You can also stop diagnostics entirely by deleting the app; iOS also lets you switch off Share iPhone Analytics under Settings → Privacy & Security → Analytics & Improvements, which limits diagnostics at the system level.

9. Changes to this policy

If this policy changes, the new version is published at this address with a new effective date. Material changes will also be noted in the App Store release notes for the version that introduces them.
