What we collect

How we use Google user data

We use Google sign-in only to authenticate you and create/maintain your Sifr Studio account (name, email, Google id). We do not sell Google user data. On The Infinite Game we send a hashed copy of your email to X so we can measure ads. We do not grant unrelated apps access to your Google account data beyond what Google OAuth returns for sign-in.

Why we process data

Processors

We use these processors to run the services:

Self-hosted Toolbox instances and any tools you point agents at are outside Sifr Studio’s control.

Cookies

Retention

Account and product data are kept while your account or project is active. You may ask us to delete your account data. Backups may retain copies for a limited period. Payment records may be kept as required for accounting and fraud prevention. Analytics events follow PostHog’s retention settings.

Your rights

Depending on where you live, you may have rights to access, correct, delete, or export personal data, or to object to certain processing. Email [email protected] and we will respond within a reasonable time. For 333 Sentences, you can also request account and associated data deletion online. You may also revoke Google access in your Google account settings.

Children

Our services are not directed to children under 16. We do not knowingly collect their data.

International transfers

We and our processors may process data in the United States and other countries. If that is not acceptable for your use case, do not use the services or contact us before signing up.

Changes

We may update this policy. The effective date above will change when we do. Continued use after an update means you accept the revised policy.
