1. Overview

The Day One Challenge is a 45-day habit-building app that combines daily devotional lessons with reflection questions. This policy explains what information the app collects, why, how it's used, and the choices you have. We aim to collect as little as possible.

2. Information we collect

Information you provide:

  • Account information (if you create an account): your name and the email address or identifier associated with your sign-in method (Sign in with Apple, Google, or email).

  • Reflection answers: the responses you write to the daily Study / Action / Gratitude questions. These are personal to you.

  • Reminder settings: the daily time and time zone you choose so the app can unlock your lesson and send your reminder at the right moment.

2. Information we collect

Information collected automatically:

  • Progress data: your current day, best day reached, run number, and completion dates, used to run the challenge and its reset rules.

  • Push notification token: a device identifier used only to deliver your daily reminder, if you enable notifications.

  • Basic technical/diagnostic data: app version, device type, and operating system, used to keep the app working and fix crashes.

We do NOT collect: precise location, contacts, photos, health records, payment card numbers (any purchases are handled by Apple, Google, or the linked program's own provider), or advertising identifiers. The app does not show third-party ads.

3. How we use information

We use the information above only to:

  • Deliver the daily lesson, cards, and reflection experience;

  • Track your progress and apply the challenge rules (including the midnight-cutoff reset);

  • Send the daily reminder you scheduled;

  • Save and sync your progress and answers to your account (if you signed in) so you don't lose them;

  • Maintain, secure, and improve the app.

We do not sell your personal information. We do not use your reflection answers for advertising.

4. How information is stored and shared

Your data is stored on your device and, if you create an account, in our backend hosted by Supabase (database and authentication). We share information only with service providers that help operate the app, under agreements that limit their use of it:

  • Supabase — database, authentication, and storage.

  • Expo / Google Firebase Cloud Messaging / Apple Push Notification service — to deliver push notifications.

  • Apple and Google — for sign-in and, where applicable, app distribution.

We may disclose information if required by law or to protect the rights, safety, and security of our users or the app.

5. The "Evolve" program and external links

The app links to Evolve Mental Health and other resources at evolvepathway.com and related sites. When you follow those links you leave the app and are subject to those services' own privacy policies, not this one. We are not responsible for the content or practices of external sites.

6. Your choices and rights

The app links to Evolve Mental Health and other resources at evolvepathway.com and related sites. When you follow those links you leave the app and are subject to those services' own privacy policies, not this one. We are not responsible for the content or practices of external sites.

  • Notifications: you can turn reminders on or off in your device settings at any time.

  • Edit your reminder time: anytime in the app's Profile.

  • Access and deletion: you can delete your account and associated data from within the app (Profile → "Delete my account & data"), which removes your progress and reflection answers from our systems. You may also contact us at [email protected] to request access to or deletion of your data.

  • Depending on where you live (e.g., EEA/UK or California), you may have additional rights to access, correct, port, or delete your personal information, and to object to or restrict certain processing. To exercise these, contact us at [email protected].

7. Data retention

We keep your account data and reflection answers for as long as your account is active. When you delete your account, we delete this data from our active systems, except where we must retain limited records to comply with legal obligations.

8. Children's privacy

The app is intended for users 13 and older (or the minimum age required in your country). It is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us information, contact us and we will delete it.

9. Security

We use reasonable technical and organizational measures — including authentication and access controls on our backend — to protect your information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

10. International users

We operate in the United States. If you use the app from outside the U.S., your information may be processed in the U.S. and other countries with different data-protection laws than yours.

11. Health and medical disclaimer

The app's lessons and neuroscience references are for education and personal growth only. They are not medical or mental-health advice and are not a substitute for professional care. If you are in crisis, contact a licensed professional or your local emergency services.

12. Changes to this policy

We may update this policy from time to time. We'll change the "Last updated" date above and, for material changes, provide notice in the app. Continued use after an update means you accept the revised policy.
