Privacy Policy
Last updated:
This policy explains what personal data Changuito handles, why, who else receives it, and how you can access or delete it.
1. Scope
This policy covers www.changuito.me, sol.changuito.me and the Changuito app for Solana Seeker (me.changuito.sol), which loads sol.changuito.me. The app’s own page at sol.changuito.me/privacidad describes in more technical detail what its code stores; this policy does not contradict it.
2. Sign-in and wallet
You can sign in with email or Google through Privy, which creates a Solana wallet on your account, or with a Solana wallet by signing a one-time message. After sign-in, the app keeps a signed session cookie for 30 days.
Changuito never asks for or receives your seed phrase or private key.
3. Supermarket account details
If you choose to save them, your supermarket account details (for Día: email, password, national ID number and postal code) are stored encrypted (AES-256-GCM) with a key that stays on the server. The password is only decrypted to place an order you asked for and is never sent back to your browser.
4. Conversations, carts and orders
When you are signed in, chat transcripts are stored linked to your wallet address. Saved checkouts (about 24 hours) include the cart, postal code, amounts and buyer; completed orders are kept in the orders table. A usage counter per address enforces message limits. Your browser also keeps chats in local storage.
What you write is sent to the AI model provider configured on the server (Anthropic by default, or OpenAI) to generate answers. Product searches go to the supermarket websites. Exchange rates come from a public quote service.
5. Blockchain data
Payments and escrow transactions are written to a public blockchain (Solana devnet in the current beta). That data is public and cannot be deleted by Changuito or by you.
6. Waitlist and bug reports on www.changuito.me
If you join the waitlist, we store the name, email, how you heard about us and, if you give it, your WhatsApp number, to contact you about the beta. If you report a bug, we store your name, email, the description and any files you attach, to fix the problem.
These forms are protected by Cloudflare Turnstile against bots. The data is kept in our own storage (a database and a private spreadsheet) and is not sold.
8. Why we use your data
To provide the service you ask for (search, carts, checkout and payments), to keep it secure and limit abuse, to contact you about the beta when you asked us to, to fix bugs, and to understand usage in aggregate. We do not sell your personal data.
9. Your rights and deleting your data
From your profile in the app you can delete your Changuito account: the encrypted profile, chats, related orders, saved checkouts, the usage counter, the session cookie and Changuito data in your browser. If possible, your Privy user is deleted too. Your supermarket account and anything already written on the blockchain are not deleted.
Under Argentine Law 25.326 you can ask to access, correct or delete your personal data. Write to contact@simonethg.com. The Agencia de Acceso a la Información Pública is the authority in charge of enforcing that law.
10. Age
Changuito is meant for adults. Some supermarket products, such as alcohol, are only for people of legal age.
11. Changes
We may update this policy. The date at the top shows the latest version; for important changes we will also tell you in the app.
12. Contact
Write to contact@simonethg.com. You can also report a problem at https://www.changuito.me/reportarbug or reach us on X, Instagram or LinkedIn (@appchanguito).
