What security measures are necessary for protecting sensitive user data in Bubbl

Go beyond basic privacy rules to create a defense-in-depth approach. For every Data Type, define rules that restrict: who can find records in searches, which fields each user type can see, who can create/modify/delete via the API. For user data specifically: personal information (email, phone, address) should only be visible to the user themselves and admins. Payment data should never be stored in Bubble — use Stripe's token-based approach. Create a test checklist: for each Data Type, verify what data a regular user, another user, a logged-out visitor, and an admin can see using 'Run as.'

Classify your data into sensitivity levels: Public (product names, blog posts), Internal (user activity, analytics), Confidential (emails, phone numbers), and Restricted (payment info, government IDs). For Confidential data, ensure privacy rules restrict access. For Restricted data, do not store it in Bubble at all — use third-party services like Stripe for payments. Never store plain-text passwords (Bubble handles this automatically), API keys in the database, or full credit card numbers. If you must store sensitive data, use a backend workflow with an encryption API to encrypt before storing and decrypt on retrieval.

For GDPR (EU) and CCPA (California) compliance, build these features: (1) Data access request — a page or workflow that exports all of a user's data as JSON or CSV. Search every Data Type for records associated with the user and compile the results. (2) Data deletion request — a workflow that deletes or anonymizes all user records. Replace personal data with anonymized values rather than deleting records that other records depend on. (3) Consent management — a cookie consent banner, data processing consent checkbox during signup, and a preferences page for managing consent. (4) Privacy policy page linking to your data practices.

Create a Security Audit checklist and run it monthly: (1) Review privacy rules on all Data Types. (2) Check API Connector for exposed keys. (3) Verify no sensitive data in HTML elements. (4) Test with non-admin 'Run as' user. (5) Review exposed API endpoints. (6) Check for unused plugins (potential attack surface). (7) Review admin user list. (8) Check Bubble's security logs (Logs tab). Use Bubble's Security Dashboard if available on your plan. Document each audit with findings and remediation actions.

Prepare for worst-case scenarios with a documented response plan: (1) Detection — monitor for unusual data access patterns, set up alerts for bulk data reads, and review logs regularly. (2) Containment — procedures to revoke API tokens, disable compromised accounts, and change credentials. (3) Notification — under GDPR, you must notify authorities within 72 hours and affected users without undue delay. Draft template notification emails. (4) Recovery — steps to restore data integrity, patch the vulnerability, and strengthen defenses. Store this plan accessibly and review it quarterly.
