Privacy Rule

A Privacy Rule in Bubble controls who can see, search, or modify specific data in your database. It acts as a security filter at the data level, not just the interface level.

Privacy Rules are essential for any Bubble app that handles user data. Without them, users could potentially access records that do not belong to them.

Key Takeaways

• Data-level security: Privacy Rules protect your database records, not just what appears on screen in your app.
• Per-data-type rules: You set Privacy Rules on each data type separately in Bubble's data settings.
• Condition-based access: Rules use conditions to allow or deny access based on user identity or role.
• Default is restrictive: Bubble recommends starting with restrictive rules and opening access only where needed.

What is a Privacy Rule in Bubble?

A Privacy Rule in Bubble is a condition-based rule that determines which users can view, search, or change records in your database. Each data type has its own set of Privacy Rules configured in the Data tab.

Privacy Rules sit between your database and your app's frontend. They run on every data request, regardless of how your UI is set up.

• User-scoped access: You can limit record access to the user who created it, so others cannot read their data.
• Role-based filtering: Rules can check a user's role or field value to decide whether access is allowed.
• Field-level privacy: You can hide specific fields on a record while still allowing the record itself to be visible.

Understanding how Bubble handles data privacy is critical before launching any app that stores personal information. Privacy Rules are your primary tool for data security inside Bubble.

How Privacy Rules Work in Bubble

Privacy Rules run as server-side filters on every database query. Even if a user tries to access data through the API or a workflow, the Privacy Rules block unauthorized access before any data is returned.

You configure Privacy Rules in the Data tab under each data type. You define who can perform each action using Bubble's condition builder.

• View all fields: Controls whether a user can read any field values on a matching record.
• Find in searches: Controls whether a record appears in search results for a given user.
• Make changes: Controls whether a user can update or delete a record they can see.

Privacy Rules stack with each other. If any rule grants access, the user gains that level of permission. If no rule matches, access is denied by default.

Why Privacy Rules Matter for No-Code Apps

Privacy Rules are not optional in Bubble. Without them, all authenticated users may be able to read and modify each other's data, which is a serious security problem for any real application.

Many Bubble apps have shipped with missing or broken Privacy Rules. This is one of the most common security mistakes in no-code development.

• Prevent data leaks: Without proper rules, a logged-in user could query and read another user's private records.
• Protect sensitive fields: Fields like payment details, addresses, or notes can be hidden even when a record is accessible.
• Pass compliance checks: Apps handling personal data need proper access controls to meet standards like GDPR.

At LOW/CODE Agency, Privacy Rules are part of our standard pre-launch security review on every Bubble app we build. Skipping this step is never acceptable on a production product.

Common Privacy Rule Mistakes in Bubble

The most common Privacy Rule mistakes are setting no rules at all, allowing too broad access, or forgetting to restrict field visibility alongside record visibility.

Even experienced Bubble builders make Privacy Rule errors. Knowing what to watch for saves you from serious vulnerabilities.

• No rules set: If you have no Privacy Rules on a data type, Bubble's default behavior may expose records to all users.
• Overly open conditions: Using "This User is logged in" without additional conditions gives all users access to all records of that type.
• Forgetting field-level rules: You can hide a record but still expose sensitive fields if field-level restrictions are not set.

Testing Privacy Rules in Preview Mode by logging in as different test users is the best way to verify your configuration is working correctly before launch.

Conclusion

Privacy Rules in Bubble are a foundational part of building a secure, trustworthy application. They protect your users' data at the database level and should be configured carefully on every data type before launch. Teams building serious products on Bubble need to treat Privacy Rules as a first-class concern, not an afterthought.

At LOW/CODE Agency, we've helped 450+ clients build and scale apps on Bubble and other no-code platforms. Our clients include global brands like Medtronic, American Express, Coca-Cola, Zapier, and Sotheby's.

Frequently Asked Questions

What happens if I have no Privacy Rules in Bubble?

Without Privacy Rules, Bubble may allow logged-in users to access all records of that data type, which is a security risk.

Can Privacy Rules block API access too?

Yes. Privacy Rules apply to all data queries including those made through Bubble's Data API and workflows.

How do I test my Privacy Rules in Bubble?

Log in as different test users in Preview Mode and check whether each user can only see the records they should.

Can I set Privacy Rules on specific fields?

Yes. Bubble lets you restrict visibility of individual fields on a data type even when the record itself is accessible.

Do Privacy Rules affect admin users too?

Yes, unless you create a specific rule that grants broader access to users with an admin role or flag.

Are Privacy Rules the same as roles in Bubble?

No. Roles are a data structure you build. Privacy Rules use those roles as conditions to grant or deny data access.
