We retain your personal data only for as long as necessary to provide the services you have requested and thereafter for legitimate legal or business purposes. These might include retention periods mandated by legal, contractual, or similar obligations applicable to our business operations; for preserving, resolving, defending, or enforcing our legal/contractual rights; or needed to maintain adequate and accurate business and financial records.

Cross-Border Data Transfers​

We store your personal data on secure servers located in data centers within the West Europe region. We may transfer personal data to a country outside of the European Economic Area (EEA) if necessary, for example, to a jurisdiction where our service providers are located. When we do, we ensure that an appropriate level of protection is in place to protect the personal data.

About Google and GitHub User Data​

Access to Google and GitHub User Data​

Logto only accesses certain Google and GitHub account information with explicit user consent. When a user signs up for Logto, they grant us access to certain account information, such as name, email address, and profile picture.

Use of Google and GitHub User Data​

Logto uses Google and GitHub user data solely for the purpose of providing our services to the user. This includes enabling the user to sign in to our app, and providing access to necessary features within Logto Cloud.

Storage of Google and GitHub User Data​

Logto stores Google and GitHub user data on secure servers located in data centers within the West Europe region.

Sharing of Google and GitHub User Data​

Logto does not share Google and GitHub user data with any third parties, except as required by law or to comply with legal process.

Information Sharing​

We do not sell, rent, or share any personal information with third parties, except as required by law, or to comply with legal process, or as necessary to provide our services.

Data Security​

We take the security of your personal information seriously and have implemented various security measures to protect it, including but not limited to:

  1. Secure Communication: The communication between any public party to Logto services is enforced by TLS (Transport Layer Security) to ensure that all data transmitted between you and our service is encrypted and secure.
  2. Private Database Network: The Logto database stays in a private network in the Azure West Europe region, with no direct access to the public internet. This ensures that your data is stored in a secure and protected environment.
  3. Data Isolation: Every tenant has a dedicated database role and every business table has enforced Row-Level Security to ensure that your data is isolated in the database. This means that only authorized users have access to the data, and each tenant's data is separated from other tenants.
  4. Password Encryption: Logto will not store passwords in plain text. All passwords are encrypted using the Argon2 algorithm, which is a secure password hashing algorithm. This ensures that even if a data breach were to occur, your password would not be compromised.
  5. Database Encryption: All data stored in the Logto database is encrypted at rest. See Information protection and encryption for more information.

We regularly review our security practices and update them as necessary to ensure that your personal information is protected. If you have any questions or concerns about the security of your personal information, please contact us at [email protected].
