Privacy Policy

This Privacy Policy explains how 66-Day Streak ("we," "our," or "us") handles information when you use the 66-Day Streak mobile application (the "App") or visit 66streaks.com (the "Website").

1. Privacy at a Glance

Your habit content stays on your device unless you choose to export it or add a habit to a calendar. No account is required. We do not receive habit names, descriptions, notes, calendar content, detailed progress history or HealthKit measurements. RevenueCat processes limited purchase and technical data to manage Premium. Starting with App version 1.9.0, Aptabase processes anonymous usage analytics, including events indicating that a habit was created or completed, without the habit’s identity or content.

2. Habit Data Stored on Your Device

The App stores habit names and icons, streak and check-in history, reminders, settings, insights, and locally created backup or export files on your device using Apple storage frameworks. We do not receive this habit data. If you create, share, or save an export, you control where that file goes.

Local notifications are generated and scheduled on your device. You can disable them in device settings.

Calendar Integration

If you enable calendar integration for a habit and grant calendar access, the App writes its title, schedule, duration, and a link back to the habit to the calendar you choose. The App reads and manages its own events to update schedules and remove future events when you disconnect. It does not send your calendar content to us or use unrelated events. Calendar edits do not change habit progress. Your calendar provider may sync these events across devices, and people with access to a shared calendar may see the habit title. You can disable the integration in the App or revoke calendar access in device settings. Revoking access prevents the App from removing existing events; you can remove them in your calendar app.

3. Purchase Data Processed Through RevenueCat and Apple

We use RevenueCat, Inc. to display offerings, validate and restore purchases, and manage Premium access. The App sends a randomly generated Support ID as its App User ID, together with the app version, habit count and selected language. It does not send RevenueCat habit names, descriptions, notes, HealthKit measurements, your name or email address.

RevenueCat may process:

• A randomly generated anonymous App User ID
• Purchase, subscription, product, entitlement, renewal, and expiration information
• Apple transaction or receipt information needed to validate purchases
• Limited technical information, such as device type, operating system, and last-seen time

We use this information only to operate Premium access, prevent purchase fraud, provide support, and understand subscription performance. We do not use it for third-party advertising or cross-app tracking.

Purchases are made through Apple's App Store. Apple processes payment and transaction information under Apple's Privacy Policy. RevenueCat processes information under RevenueCat's Privacy Policy.

4. Anonymous App Analytics (Aptabase)

We use Aptabase to understand app usage and improve the App. Events include app launches, onboarding completion, habit creation and completion, habit counts and general types, completion source (such as manual, widget or HealthKit), feature and achievement use, paywall interactions, and purchase, restore and Premium-expiration events with product IDs. These events do not include habit names, descriptions, notes, reminder times, health measurements, email addresses, Support IDs, habit IDs or transaction IDs.

Aptabase receives the event time, operating system and version, device model, app version and build, language, SDK version and a temporary session ID. It derives country and region from the connection’s IP address without storing the IP itself, and creates an app-specific pseudonymous hash that changes daily. We do not request precise location. Aptabase does not receive persistent user or device identifiers, and we do not use it for advertising, cross-app tracking, screen capture or session recordings.

Our Aptabase Cloud account uses the EU region. According to Aptabase’s Privacy Policy, EU analytics are processed and stored in the European Union and analytics data may be retained for up to five years. Deleting the App does not delete previously sent anonymous events.

5. Website Data

The Website automatically loads Google Tag Manager, Google Analytics, and Microsoft Clarity to measure visits and improve the Website. They may process pages viewed, interactions, referring pages, browser and device information, IP address, cookies or similar identifiers, and—through Clarity—session recordings and heatmaps. You can limit cookies and similar technologies through your browser or device settings. Google handles information under Google's Privacy Policy; Microsoft handles information under its Privacy Statement.

6. How and Why We Use Information

We process limited information where needed to perform our contract with you (provide purchases and Premium access), pursue legitimate interests (secure and improve the App and Website), comply with law, or where consent is required by applicable law.

7. Sharing, Sale, and Advertising

We share information only with service providers needed for the purposes above, including Apple, RevenueCat, Aptabase, Google, Microsoft, and infrastructure providers. We do not sell your personal information. We do not use your App data for targeted advertising, and the App does not include an advertising SDK.

8. Retention and Deletion

Deleting the App removes data stored locally by the App, subject to any device backups or exports you created. It does not automatically delete records held by Apple or RevenueCat. Purchase records may be retained as needed to provide entitlements, comply with legal and accounting duties, resolve disputes, and prevent fraud.

For access or deletion requests about information under our control, email us. You can copy your Support ID from Settings to help us locate your RevenueCat record. This ID may remain in the device Keychain after uninstalling the App. Anonymous Aptabase events cannot be reliably associated with an individual for access or deletion. Apple handles App Store transaction requests through its own privacy process.

9. International Processing and Security

Our providers may process information in countries other than yours, including the United States, using safeguards required by applicable law. We and our providers use reasonable administrative, technical, and organizational safeguards, but no method of transmission or storage is completely secure.

10. Children's Privacy

Minors should use the App only with permission and supervision from a parent or legal guardian. We do not ask users to provide direct personal identifiers. If Premium is purchased, Apple and RevenueCat process the limited purchase and technical information described above. A parent or guardian may contact us with questions or requests.

11. Your Rights

Depending on where you live, you may have rights to access, correct, delete, restrict, object to, or receive a copy of personal information, and to withdraw consent. You may also complain to your local data protection authority. These rights may be subject to legal exceptions.

12. Changes to This Policy

We may update this policy when our practices or legal obligations change. We will post the revised policy here and update the date above.
