Data we collect and store

Infrastructure and network security

Security is a non-negotiable priority at Fillout. We take the following measures to keep your data and account secure.


Fillout is hosted on the Google Cloud Platform (GCP, via and our GCP/Render servers are located in the United States and in the European Union (EU). EU servers are only used if requested by the customer. GCP data centers have state-of-the-art physical access controls, logical access controls, and frequent third-party independent audits. Google has published a detailed security whitepaper outlining these measures.
Fillout employees have as-needed access to infrastructure on Render. All employees have dedicated user accounts and access infrastructure via two-factor authentication.


All data in transit is encrypted over HTTPS/TLS between you and Fillout's servers. All data is encrypted at rest and replicated for durability. We offer an optional feature to encrypt submission data with your own public/private key.

Application security

Two-factor authentication and single sign-on

Fillout supports G Suite SSO, allowing customers to enforce that users sign in using customer-managed identity providers. Two-factor authentication for application login can be enforced at the identity provider level (e.g. by turning it on within G Suite).
Contact us to enable other SSO providers, like Okta, Active Directory, or other SAML providers.

Business continuity and disaster recovery

Business Continuity

Fillout keeps daily and point-in-time encrypted backups of data on While never expected, in the case of production data loss, we are able to restore customer data from these backups.

Disaster Recovery

In the event of a region-wide outage, Fillout will bring up a duplicate environment in a different Google Cloud Platform region. Fillout infrastructure is designed to be portable and restorable under different regions.
