Privacy Policy

Revive Arc is a Winter Arc habit tracker. You pick a 30, 60, or 90-day Arc, build daily habits, join shorter challenges, log focus sessions, and earn XP, streaks, levels, and achievements.

This policy applies to this website and to the Revive Arc Android app (package com.revive.ai, version 4.1.1). We handle all personal data in compliance with applicable data protection laws and Google Play developer policies.

We collect only the information necessary to operate Revive Arc:

• Account and identity data: When you create an account or sign in with email or Google, we collect your email address, display name, and avatar URL through Supabase authentication (email sign-in and Google ID-token sign-in). There are no guest or anonymous accounts.
• User content: The Arcs, habits, habit logs, challenge logs, focus sessions, and XP events you create in the app. This includes your profile avatar image, stored as avatars/<userId>/avatar.jpg, and your local reminder preferences for daily, habit, and focus reminders.
• Usage and device data: Basic technical data recorded automatically, including operating system, app version, and access timestamps, used to keep the service reliable and secure.
• No payments or financial data: Version 1 of the app offers no in-app purchases, so we do not collect payment card numbers, billing details, or purchase records.
• No advertising trackers: We do not use third-party behavioral advertising trackers, and we do not collect advertising identifiers for ad targeting.

The Android app requests only the device permissions it needs to function. You can grant or deny these in your system settings:

• Photos / images: Used when you choose a profile avatar image to upload to your account.
• Media library: Used when you choose to save an image from the app to your device gallery.
• Notifications: Used for daily, habit, and focus reminders you enable, delivered through Android notification channels.
• Google Sign-In: Used only when you choose to sign in with your Google account.
• Secure on-device storage: Used to keep your login session on your own device.
• Not used: The app does not use the camera or the microphone.

We use your personal data for the following purposes:

• Core service delivery: To run your Arcs, habits, challenges, focus sessions, XP, streaks, levels, and achievements, and to sync your progress to your account.
• Account management: To authenticate your identity, manage login sessions, protect account security, and sync your profile across your devices.
• Reminders: To send the daily, habit, and focus reminders you have enabled in the app.
• Support and security: To respond to support requests, diagnose technical issues, prevent abuse, and maintain service stability.

We retain personal data only for as long as necessary to provide the service or as required by law:

• Account data: Retained while your account is active. After you request deletion, your account data is permanently purged within 30 days.
• User content: Your Arcs, habits, logs, focus sessions, XP events, and avatar image remain stored while your account is active or until you delete them. Deleted content is purged from active production systems within 30 days.
• System backups: Automated encrypted backups are kept for disaster recovery and are overwritten on a rolling 30-day rotation.
• No long billing retention: Because the app has no in-app purchases, we keep no long-term billing or purchase archives.

You have full control over your personal data:

• In-app controls: You can delete individual habits, challenges, and logs at any time from inside the app. Ending an Arc ("End Arc") closes the current Arc but keeps your history — it does not erase your account.
• Full account and personal data deletion request: To permanently delete your account and all associated personal data, send an email to 9thumb.in@gmail.com from the email address registered to your Revive Arc account.

Upon receiving your request, we will verify your identity and permanently delete your account profile, authentication record, Arcs, habits, logs, focus sessions, XP events, and stored avatar image within 30 days. We will send a confirmation email to your registered address once the deletion is complete.

We do not sell, rent, or trade your personal data. We share data only with the providers needed to operate the service:

• Backend infrastructure: Supabase Inc. for account authentication, database hosting, and file storage, including the project backend at fwvilqtajlkgveoncxoq.supabase.co, under strict access controls.
• Build infrastructure: Expo / EAS build services used to compile and distribute the Android app package.

We share data with no advertising networks and no data brokers. Each provider processes data only on our behalf under confidentiality obligations and applicable data protection standards.

All traffic between the app and our backend is encrypted with HTTPS/TLS. Database records are protected by PostgreSQL Row Level Security policies so each user can access only their own data.

Your login session on your device is held in secure on-device storage (AES-256 encrypted session storage), so your credentials are not kept in plain text on the device.

Our services are not directed to children under the age of 13 (or under 16 in the European Economic Area). We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, contact us at 9thumb.in@gmail.com and we will delete the information promptly.

Depending on your location, you may have rights under data privacy laws such as the GDPR or CCPA, including:

• The right to access and receive a copy of your personal data.
• The right to rectify inaccurate or incomplete information.
• The right to request the deletion of your personal data.
• The right to restrict or object to certain processing activities.
• The right to withdraw consent at any time without affecting prior lawful processing.

To exercise any of these rights, contact us at 9thumb.in@gmail.com.

We may update this Privacy Policy from time to time to reflect changes in our services or legal requirements. When changes are posted, we will revise the updated date at the bottom of this page.

If you have any questions, concerns, or requests regarding this Privacy Policy, your data retention, or data deletion, contact us at:
