Privacy Policy

BLOCKRN (“we,” “us”) blocks apps on your phone and gives friends control over how you get back in. This policy explains what we collect, why, and what actually happens to it — described here as plainly as the mechanic itself works.

1. Account & profile data

When you create an account we store a username, a push notification token, and your current streak. If you add a profile photo, it's stored as an image file tied to your account.

2. Friends and schedules

We store your friend connections and the block schedules and manual sessions you set up, so your squad can be alerted when you call for help. Friends you add can see your schedules and whether you're currently locked out.

3. Passphrases

When a friend sets your passphrase, we store it — both hashed and in plain text — so the app can display it to your blocker UI and verify it against your spoken attempt. This means the friend who set your passphrase, and BLOCKRN's systems, can see it in plain text. Don't use a passphrase that's also a password you use elsewhere.

4. Microphone & speech recognition

BLOCKRN uses your microphone to verify a spoken passphrase. Depending on how you're unlocking, this happens one of two ways:

• Standard unlock: your device's own speech recognizer (iOS Speech framework / Android Speech Recognizer) listens for your passphrase. Depending on your device settings, this recognition may be processed on-device or by Apple's or Google's speech services — that's platform behavior, not something BLOCKRN controls.
• Friend-forced voice unlock: your voice is recorded and sent to our server, which passes it to OpenAI's Whisper API for transcription. The recording is used only to check it against your passphrase and is not saved afterward — we don't keep a copy of your voice.

5. Contacts

If you grant contacts access, we read your contact list on-device to help you pick who to invite — your contact list itself is never uploaded to our servers. If you choose to send someone an SMS invite, we store a one-way hash of that phone number so we can avoid sending duplicate invites. We do not automatically match your contacts against other BLOCKRN users.

6. Face ID

If you enable it, Face ID is used only to lock BLOCKRN's own settings on your device. It's handled entirely by your device's operating system — we never receive your biometric data, and the setting itself is stored only on your device.

7. Push notifications

We send push notifications — distress calls, unlock requests, and similar friend activity — through Expo's push notification service using your device's push token.

8. Payments

Subscription and purchase handling is managed through RevenueCat. If you subscribe, purchase and entitlement data is shared with RevenueCat under their own privacy practices, which you can review at revenuecat.com/privacy.

9. What we don't do

We don't use third-party analytics or advertising SDKs. We don't sell your data. We don't track you across other apps or websites.

10. Your choices

You can revoke microphone, speech recognition, contacts, or Face ID permission at any time in your device settings — some features (like voice unlock) won't work without them. To request a copy of your data or account deletion, email hello@blockrn.com.

11. Children

BLOCKRN is not directed at children under 13, and we don't knowingly collect data from them.

12. Changes to this policy

If this policy changes materially, we'll update the date above and, where required, notify you in the app.
