Privacy Policy

Last updated: August 25, 2026

Hashnag is a notification app: creators claim hashtag topics and “ring” them to subscribers. This policy describes what we collect and why.

What we collect

• Phone number — used to sign you in with a one-time code and to identify your account. We never send marketing texts.
• Profile data — the handle, display name, bio, interests, and optional profile photo you choose to provide.
• Push token & timezone — your device’s push notification token (so rings can reach you) and timezone (so quiet hours work).
• Activity — topics you create or subscribe to, rings you send, and read state. This is the product working, not tracking.
• Waitlist — if Hashnag isn’t open in your country yet, we keep the number you entered and your device’s notification token so we can tell you when it is. No account is created. We delete the entry as soon as you sign up, or on request; if a country stays closed we delete unnotified entries after 12 months.

What we don’t do

• No ads, no ad tracking, no sale of your data — to anyone, ever.
• No contact upload, no location collection, no analytics profiles of your behavior.
• No SMS other than the sign-in codes you request.

Where your data lives

Data is stored on Amazon Web Services (US East). Push notifications are delivered via Expo’s push service and Apple/Google’s notification systems, which process your push token for delivery.

Sign-in codes are sent by our verification providers, who receive your phone number in order to deliver the message: Google (Firebase Authentication) for numbers in the United States and Canada, and Twilio for other countries as they open. They process the number to send and verify the code, and for their own fraud prevention.

Deleting your account

Settings → Delete account removes your account and its data (profile, topics, subscriptions, devices, rings’ authorship) immediately and permanently. This also deletes the sign-in record held by our verification provider, and any waitlist entry for your number.
