Privacy Policy

1 Who is responsible for your data

BBH is developed and published by Zydeno Studio, an independent mobile studio. Under privacy law, Zydeno Studio is the “data controller” for the purposes of the EU General Data Protection Regulation (GDPR), the UK GDPR, the California Consumer Privacy Act (CCPA/CPRA), and equivalent frameworks.

For any privacy-related request, contact us at [email protected]. We respond within 30 days.

2 What information BBH handles

2.1 Information stored locally on your device

BBH stores the following categories of information in a local database on your phone so the app can function:

• Habits you choose to track — name, category, icon, color, start date, target or notes you add.
• Events you log — relapse timestamps, freeze-day usage, milestone achievements.
• Journal entries — any text, reflection, or trigger you choose to record.
• Mood check-ins — the mood score and optional note you enter at check-in time.
• App preferences — your chosen theme, language, sound and haptic settings, reminder time, and notification toggles.

This data is written to a local database (Android Room) and a local preferences store (Android DataStore), both stored inside the app’s private sandbox on your device. Other apps cannot read it. We cannot read it. No copy is sent anywhere.

2.2 Information BBH does not collect or send

• No personal identifiers (no name, no email, no phone number, no account).
• No device identifiers (no advertising ID, no IMEI, no Android ID collected by us).
• No usage analytics, session recording, crash telemetry, or behavioural tracking.
• No location data, contacts, photos, microphone, or camera access.
• No social-graph integrations (no Facebook, Google, Apple, or other sign-in).
• No third-party advertising, attribution, or marketing SDKs.

2.3 Automatic cloud backup

BBH explicitly opts out of Android’s Auto Backup feature (allowBackup=“false” in the app manifest). This means Google Drive will not automatically back up your BBH data under your Google account. This is deliberate — to keep sensitive recovery-tracking data strictly on your device.

3 Permissions the app requests

BBH requests only the minimum Android permissions necessary to function:

• Notifications (POST_NOTIFICATIONS) — required on Android 13 and later to display the reminders and milestone celebrations you opt into. You may deny this permission or revoke it at any time in system settings; the app still works, you will simply not receive reminders.

BBH does not request any other runtime permissions. The app does not require location, contacts, camera, microphone, storage, or network-state permissions.

4 Third-party services

None. BBH does not integrate with any third-party analytics, crash-reporting, advertising, or attribution service. There are no SDKs that transmit data off your device.

If we ever add such a service in a future version of the app, we will update this Policy, disclose it prominently in the app’s Google Play “Data safety” section, and — where required by law — request your explicit consent before any data leaves your device.

5 Storage, retention, and deletion

Because all data is stored locally in the app’s private sandbox, retention is entirely under your control:

• Delete a single item — swipe or use the delete action in the app; the entry is removed from the database immediately.
• Clear everything — open Android Settings → Apps → BBH → Storage → “Clear data”. This wipes all habits, events, journal entries, moods, and preferences.
• Uninstall the app — this removes the app and all its associated data from your device.

We do not retain any copy of your data after you delete it, because we never had a copy in the first place.

6 Optional backup files you create

BBH includes an “Export backup” feature that lets you save your data as a JSON file to a location you choose (for example, your device’s Downloads folder, Google Drive, or a cloud file manager). This file is created and controlled by you.

Once exported, the file leaves BBH’s sandbox and is subject to the privacy rules of wherever you store it. If you upload it to a third-party cloud service, that service’s privacy policy applies. We strongly recommend keeping backup files private and deleting them after you restore from them.

7 Children

BBH deals with topics related to addiction recovery and habit change, and is therefore not directed at children. The app is intended for users aged 18 and over.

We do not knowingly collect any data from:

• Children under 13 (United States — COPPA);
• Children under 16 (European Economic Area — GDPR);
• Persons under the minimum digital-consent age in any other applicable jurisdiction.

If you are a parent or guardian and believe your child has installed and used the app, you can delete all data by uninstalling the app from their device. Contact [email protected] if we can assist further.

8 Your privacy rights

Because all your data stays on your device and we do not process it remotely, the traditional privacy rights below are fulfilled locally and instantly — no request to us is required for any of them:

• Right of access — open the app and view your data; you already have it.
• Right to rectification — edit any entry directly in the app.
• Right to erasure (“right to be forgotten”) — delete entries individually, clear app data in Android settings, or uninstall.
• Right to data portability — use the in-app “Export backup” feature to obtain your data in a structured, machine-readable JSON format.
• Right to restrict or object — you can toggle notifications, sound, haptics, and reminders at any time in app settings.

If you reside in the European Economic Area, the United Kingdom, or another GDPR-aligned jurisdiction, you also have the right to lodge a complaint with your national data-protection supervisory authority. If you reside in California, you have the additional right to opt out of the “sale” or “sharing” of personal information — we do neither — and the right to non-discrimination for exercising your rights.

If you have a privacy question we haven’t addressed, email us at [email protected].

9 Security

Your data is stored inside the app’s private Android sandbox and is protected by the operating system’s app-isolation model. Other apps on your device cannot read it without root access. We recommend that you also protect the device itself with a lock screen (PIN, pattern, or biometric) for additional security.

No system is perfectly secure. If we ever become aware of a security issue affecting BBH users, we will publish notice on our website and, where applicable law requires it, notify the relevant authorities.

10 International users

BBH is distributed globally through Google Play. Because no data leaves your device, no international data transfer occurs. Your data is processed on your device, wherever you are.

11 Changes to this Policy

We may update this Policy if the app gains features that change how data is handled — for example, if optional cloud sync is ever introduced. The “Effective” date at the top of this page reflects the latest version. Material changes will be announced within the app and on this page at least 14 days before they take effect. Continued use of BBH after an update takes effect constitutes acceptance of the updated Policy.

12 Google Play “Data safety” disclosure

The Google Play “Data safety” section for BBH declares: no data collected, no data shared. This matches the reality described in this Policy. If you ever see a mismatch between our Play Store disclosure and this Policy, please report it to [email protected] so we can correct it immediately.
