Privacy policy

What Aishou is

Aishou recommends titles based on the ratings you give. This policy explains which data we use, why, and how you control it. For privacy matters, write to contato@aishou.app.

Data we store

From the account you sign in with: your email and, for Google or Discord, the account identifier. We never receive your password. If you sign in with an email link, we store only the address.

Your ratings and the date each one was last changed.

If you import a list, your MyAnimeList username and that list's ratings.

A protected version (hash) of your session token, to keep you signed in.

Email sign-in links are stored in protected form (hash) for up to 15 minutes, or until used.

Temporary technical data

To limit abuse, we count requests per account and per IP address, in counters that erase themselves within a day. Our servers also log access, including the IP address, to keep the service working and secure.

What we use it for

To create your account, keep you signed in, save your ratings and compute your recommendations.

Your ratings are also used, without your email, to train and evaluate the recommendation models, including in academic research. Published results are aggregates only.

Who we share it with

We don't sell your data. We use Google and Discord for sign-in, Resend to send sign-in links by email, Hetzner to host the service and Cloudflare for the domain and the contact email. When you import a list, the username you enter is sent to MyAnimeList. Servers may be located outside Brazil.

Cookies and browser storage

We use one essential cookie to keep your session and, during Discord sign-in, another that lasts up to 10 minutes and stops other sites from completing the sign-in for you. We also store in your browser whether the results screen was open. Google's button may use its own cookies. We don't use advertising cookies.

How long we keep it

We keep your data while your account exists. When you delete your account, the account, ratings and sessions are erased immediately; backup copies are removed within 14 days.

Your rights

You can delete your account at any time with the Delete account button at the top of the site. Under Brazil's data protection law (LGPD), you can also ask for access, correction or information about how your data is used, at the email above.

Children

Aishou is not intended for children under 13.

Changes

If this policy changes, we'll update the date at the top of this page.
