Privacy policy

Last updated 11 October 2026

Tinge sends one-tap signals between people and groups. It is built to need very little about you: the context that picks a signal is read on your phone and reduced there to a few coarse hints, and your location never leaves the phone.

Who we are

Tinge is operated by 30labs (CNPJ 36.742.159/0001-29), Brazil, the controller of your personal data. For anything about your data, write to privacy@gettinge.app.

What we collect

• Your account: the email address, or the Apple or Google identity, you sign in with, and the display name you choose.
• Your connections: the people you connect with, the groups you create or join, the invites you send and answer, and the people you block.
• The signals you send: which signal, from whom, to which person or group, when, and whether you picked it or Tinge suggested it. A signal carries no text.
• Push tokens: an identifier for each device you are signed in on, so signals reach you as notifications.
• Coarse context, when you tap: if you allow Tinge to read context, a tap sends a handful of hints to pick a signal: a broad activity (such as walking or driving), a place category from your own saved places (such as home or work), whether you just arrived or left, and the part of the day. These hints are used to answer that tap and are not stored.

What never leaves your phone

• Your location, and the short trail of recent positions used to tell arriving from leaving.
• Your motion and activity readings.
• Your saved places, their names and where they are.

Tinge reads location only while you use the app, never in the background.

Why we use it

We use your data only to run Tinge: to sign you in, show you your people and groups, suggest a signal, deliver signals and notifications, keep the service secure, and act on blocks. This is necessary to provide the service you asked for (LGPD art. 7, V; GDPR art. 6(1)(b)). Reading context on your phone happens only with your consent, which you can withdraw at any time in your phone's settings. We do not sell your data, show ads, or use it to profile you.

Who processes it for us

• Supabase: hosts the database, sign-in and server functions, in São Paulo, Brazil.
• Expo: relays push notifications.
• Google Firebase Cloud Messaging and Apple Push Notification service: deliver notifications to Android and iPhone.
• Apple and Google: sign you in, when you choose them.
• Cloudflare: serves this website.

A notification carries the sender's name, the signal and the group name. Some of these providers process data outside Brazil, under their own safeguards for international transfers.

How long we keep it

• Your account, connections and groups: until you delete your account.
• Signals: linked to the people and groups involved for at most 90 days. After that we remove who sent them and to whom, and keep only the anonymous signal and its time, to understand how Tinge is used.
• Push tokens: until you sign out on that device, or the device stops accepting notifications.

Deleting your account

In the app, open Settings and choose Delete account. This deletes your account, profile, connections, invites, blocks and push tokens straight away. Groups you own are deleted with everything in them; in other groups, you are removed. Signals you sent or received lose any link to you. If you can't open the app, see how to delete your account.

Your rights

You can ask to access, correct, export or delete your data, to know who we share it with, and to object to or restrict how we use it. Write to privacy@gettinge.app and we will answer within 15 days. You can also complain to Brazil's data protection authority (ANPD) or, in the European Union, to your local supervisory authority.

Children

Tinge is not meant for children under 13, and we do not knowingly collect their data. If you believe a child has an account, write to us and we will delete it.

Changes

If we change this policy, we will update this page and its date, and let you know before a change that affects how we use your data takes effect.
