Guide
Is my Bubble app secure?
A Bubble app is secure only if its privacy rules are set correctly, because without them the app's data can be read through the API by anyone. The most common Bubble mistake is data exposed because privacy rules were left open, and it is checkable from the outside.
Bubble's privacy rules are the control
Bubble runs the backend for you, which removes a lot of the risk, but the privacy rules that decide who can see which data are yours to configure. Leave them open and the data types are readable through Bubble's own API, even for fields the interface never shows. Many Bubble apps ship this way without knowing.
Without privacy rules, Bubble data can be read straight through the API.
What to check
- Privacy rules on every data type, scoped so a user only sees their own records.
- No sensitive fields exposed to the API that the UI hides but the data layer returns.
- Security headers and a sensible cross-origin policy on the served pages.
Scan your Bubble URL with Plaintext to see what the app exposes from the outside.
Frequently asked
Is Bubble secure?
Bubble handles the infrastructure, but the privacy rules that protect your data are yours to set. Without them, data types are readable through Bubble's API, so the security of a Bubble app depends on those rules being correct.
Can people see my Bubble data?
If privacy rules are open, yes, through Bubble's data API, including fields the interface hides. Set privacy rules scoped to each user to close it.
