Privacy Policy

Grotesk is a terminal app for macOS made by Breno Guerra. This policy explains, plainly, what data the app uses, why, and how you can delete it. It follows Brazil's General Data Protection Law (LGPD, Law No. 13,709/2018).

In short

• We keep only what your account needs: your email and, if you sign in with Google, your name.
• Nothing you do in the terminal leaves your Mac: commands, output, files and history stay on your computer.
• No ads, no tracking, no selling of data.
• You delete your account inside the app, right away.

What data we use

To create and keep your account:

• Your email address.
• If you sign in with Google: your Google account's name and the identifier Google assigns to it. We don't access your email, contacts, files or any other data in your Google account.
• The dates your account was created and when you last signed in.
• Technical logs of connections to the account service (such as IP address and date), kept by our provider for a limited time, for security and to fix problems.

What we don't collect: the commands you type, what they show, your files, your history, the code the AI tools change and what appears in the app's browser. All of that is processed only on your Mac. When you use an AI tool inside Grotesk (such as Claude, Codex or Gemini), the conversation happens directly between you and that tool's company, under its own terms.

What we use it for

We use this data only to identify you, give you access to Grotesk and keep the service secure. The legal basis is the performance of the app's terms of use (LGPD, art. 7, V). We don't use your data for advertising or to build profiles.

Use of Google data

When you sign in with Google, we receive only your name, your email and your account identifier. We use this data solely to create and identify your Grotesk account. We don't use it for any other purpose, we don't sell it and we don't share it with third parties, except the account provider described below, which sign-in needs to work. Grotesk's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Who we share it with

• Supabase, which runs our account service. The data is stored on servers in the São Paulo region.
• Resend, which sends the sign-in emails. It receives only your email address and the sign-in email itself, and keeps a record of the delivery (recipient, subject and date) for a limited time. Sending happens from the São Paulo region.
• Google, only if you choose to sign in with Google, to confirm your identity.

Supabase, Resend and Google are companies based in the United States, so data may be processed outside Brazil, under the safeguards of the LGPD and those companies' policies. We don't sell or rent data to anyone.

How long we keep it

For as long as your account exists. When you delete your account, the account and its data are removed right away. The providers' technical logs expire on their own after a short period.

How to delete your account

In Grotesk, open Ajustes → Conta → Apagar conta… (Settings → Account → Delete account) and confirm. The account and the data tied to it are deleted right away, for good. The terminal and your files are not affected. You can also ask for deletion at the email below.

If you signed in with Google, you can also remove Grotesk's access to your Google account at myaccount.google.com/connections.

Your rights

Under the LGPD (art. 18), you can ask at any time for: confirmation that we process your data, access to it, correction, portability, deletion, information about who we share it with, and withdrawal of consent. Just write to the email below; we reply within 15 days.

Security

Connections to the account service are encrypted (HTTPS). On your Mac, your session is stored in the macOS Keychain. Sign-in uses PKCE, so an intercepted sign-in link is useless to anyone else.

Children

Grotesk is not meant for children under 13 and does not knowingly collect their data.

Changes to this policy

If this policy changes, the date at the top is updated. Important changes will also be announced in the app.
