Privacy Policy

Effective March 25, 2026

Facedown ("the App") is developed and operated by Sen Huang. This Privacy Policy explains what data we collect, how we use it, and your rights regarding that data.

Data We Collect

Anonymous user ID — generated automatically via Firebase Authentication (anonymous sign-in). We do not collect your name, email, or phone number for authentication.
Display name — a name you choose to show your partner. This is entered manually and can be changed at any time.
Bypass timestamps — when you break through an app block, the date and time are recorded.
Device tokens — used for push notifications via Firebase Cloud Messaging. Tokens are stored per-device and used only to deliver notifications you have opted into.

How We Store Your Data

All data is stored in Firebase Firestore, hosted on Google Cloud Platform. Data is encrypted in transit and at rest per Google Cloud's security standards.

Data Shared With Your Partner

When you pair with a partner in Facedown, the following data is shared with them:

Your display name
Your bypass timestamps (when you broke through a block)
Your current streak data

This sharing is the core purpose of the App. No data is ever sold to or shared with advertisers, data brokers, or any other third parties.

Third-Party Services

Facedown uses the following Firebase services provided by Google:

Firebase Authentication (anonymous sign-in)
Firebase Firestore (data storage)
Firebase Cloud Messaging (push notifications)
Firebase App Check (abuse prevention)

These services are subject to Google's Firebase Privacy Policy.

What We Do Not Collect

No analytics or usage tracking
No advertising SDKs or ad identifiers
No location data
No contacts, photos, or other personal media
No browsing history or app usage details (only bypass events are recorded)

Data Deletion

You can delete your account and all associated data at any time from within the App via Settings → Delete Account. This permanently deletes:

Your user record and display name
All partnership data
All bypass history
Your Firebase authentication record
All device tokens

Deletion is immediate and irreversible.

Children's Privacy

Facedown is not directed at children under 13 years of age. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided data to us, please contact us and we will delete it promptly.

Your Rights (CCPA / GDPR)

Depending on your jurisdiction, you may have the right to:

Request a copy of your data
Request deletion of your data
Opt out of data sharing (note: partner sharing is integral to the service)

To exercise these rights, contact us at sen@facedown.app. We will respond within 30 days.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated effective date. Continued use of the App after changes constitutes acceptance of the revised policy.
