Privacy Policy

Last updated: September 15, 2026

Authlier keeps its data collection minimal. This policy explains the little information we collect, why we collect it, and how we handle it.

Who we are

Authlier ("we", "us", or "our") operates this authentication service. We are the data controller for the information described in this policy.

What we collect

We collect only the minimum information required to run the service:

  • Your account – the email address you use to sign up for Authlier and a securely hashed version of your password.
  • Your app's users – when you use Authlier to provide authentication to your own users, we store their usernames, email addresses, hashed passwords, and the session tokens needed to sign them in.

We do not collect payment details, location, device fingerprints, or anything beyond what is necessary to authenticate users.

How we use it

We use this information solely to operate the service: to create and manage accounts, issue and validate authentication tokens, handle password resets, and keep the service secure (for example, by limiting repeated failed login attempts).

How we share it

We do not sell, rent, or share your personal information with third parties. We only disclose information when we are legally required to do so.

Security

Passwords are stored only as secure one-way hashes. We use time-limited session tokens and standard protections, such as rate limiting, to protect accounts.

How long we keep it

We keep account and authentication data only as long as it is needed to provide the service, or until you ask us to delete it.

Your rights

You may request access to, correction of, or deletion of the personal information we hold about you. To exercise any of these rights, contact us using the details below.

Children's privacy

Authlier is not directed at children, and we do not knowingly collect information from them.

Changes to this policy

We may update this policy from time to time. If we make material changes, we will update the date at the top of this page.
