Privacy Policy

Last updated: September 4, 2026 · Applies to the Sangre Fría website, web portal and the Sangre Fría iOS app

The short version. We collect the minimum needed to run your account and save your work. We do not sell your data, we do not share it with advertisers, and the app contains no advertising, no analytics SDKs and no third-party trackers. You can delete your account and everything in it from inside the app at any time.

Who we are

Sangre Fría is operated by Rafael Figueredo (New York, USA), the data controller for the information described here. Contact: falalony@gmail.com.

What we collect

That is all. The app does not request or collect your location, contacts, photos, microphone, camera, health data, or any advertising identifier.

What we do with it

Only three things: sign you in, save and sync your progress and written work across your devices, and give you access to what you paid for. We also use your email to answer support requests. We do not use your data to profile you, target ads or train models, and we do not sell or rent it to anyone.

Who else touches the data

They act as our service providers. No one else receives your data, and we share nothing with advertisers or data brokers. We disclose data only if legally required.

Where your written work goes

Your exercises and journal entries are personal and are stored with your account so you can come back to them. They are never published, never shown to other students, and never used as marketing material.

Deleting your account

In the iOS app: Settings → Delete my account. In the web portal, or by writing to falalony@gmail.com. Deletion removes your profile, your progress and everything you wrote, and it cannot be undone. We keep only the minimal record of the purchase itself, which we are required to retain for tax and accounting purposes.

How long we keep it

For as long as your account exists. If you delete your account, your personal data is removed; server logs roll off on our provider's normal retention schedule.

Security

All traffic runs over HTTPS. Passwords are stored hashed. On your phone, your session token is kept in the device's secure keychain, not in plain storage.

Children

Sangre Fría is intended for adults. It is not directed at children under 13 and we do not knowingly collect data from them.

Your rights

You can ask for a copy of your data, a correction, or its deletion by writing to falalony@gmail.com. We answer within 30 days.

Changes

If this policy changes, the date at the top changes with it, and material changes are announced in the app and the portal.
