Privacy Policy

Last updated: March 25, 2025

Overview

Deylik ("we", "our", or "the app") is a daily habit tracking app for iOS. We are committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.

Data We Collect

  • Email address — collected when you sign in via Google OAuth or magic link. Used solely for authentication.
  • Habits and logs — the habits you create and your daily progress entries. Stored securely in your account.
  • App preferences — theme and display settings, stored locally on your device.

We do not collect device identifiers, location data, contacts, or any information unrelated to habit tracking.

How We Use Your Data

  • To authenticate you and sync your habits across devices.
  • To display your progress, streaks, and completion history within the app.
  • To restore your data if you reinstall the app or switch devices.

We do not sell, rent, or share your personal data with third parties for advertising or marketing purposes.

Data Storage

Your data is stored on Supabase, a secure cloud database platform. Data is encrypted in transit (TLS) and at rest. Supabase infrastructure is hosted on AWS and complies with SOC 2 Type II standards.

Authentication

Sign-in is handled via Supabase Auth. When you choose Google sign-in, authentication is managed by Google. We only receive your email address — we do not receive your Google password or any other Google account data.

Data Retention & Deletion

Your data is retained as long as you have an active account. You can delete your account and all associated data at any time by contacting us at hello@deylik.app. Deletion is permanent and irreversible.

Children's Privacy

Deylik is not directed at children under 13. We do not knowingly collect personal information from children under 13.

Changes to This Policy

We may update this policy from time to time. We will notify you of significant changes by updating the "Last updated" date at the top of this page.
