Bubble Diagram Maker

Bubble Diagram Maker Privacy Policy

Last updated: October 2026

Summary

Bubble Diagram Maker has no network features and no third-party SDKs. Your diagrams are saved on your device and only leave it when you export or share them yourself.

This policy covers the Bubble Diagram Maker app for iPhone and iPad, published by mk0.net, an independent app studio. It is written from what the app actually does in its code. Questions: [email protected].

What we receive

Nothing. We have no accounts or servers for this app, and nothing you enter in it is sent to us.

What stays on your device

  • Your diagrams are saved on this device.
  • Your language choice and a few app preferences are stored on this device.
  • Exported files are created on this device just before you share or save them.

We cannot see this data. It is not uploaded to us.

Permissions the app may ask for

  • Photos: Asked when you save an exported diagram image to your photo library. The app can only add images, not read your library.

Every permission is optional and can be changed later in the iPhone Settings app. Features that need a permission you decline simply stay unavailable.

Data that leaves your device

None. The app does not send your data anywhere.

Ads, tracking and analytics

No ads, no tracking across apps or websites, and no data sold. The app contains no analytics SDK.

Account

No account needed. There is no sign-in.

Children

Bubble Diagram Maker is not directed at children under 13, and we do not knowingly collect personal information from children.

Keeping and deleting your data

You can delete diagrams from the diagram list. Diagrams you exported to Photos or Files stay there. Deleting Bubble Diagram Maker removes all of its data from this device.

Your rights

Depending on where you live (for example under the GDPR, UK GDPR, CCPA or KVKK), you have the right to access, correct, export or delete your personal data. Because the app keeps your records on your own device, you can do most of this directly in the app or by deleting it. For anything else, or for data held by a service listed above, email [email protected] and we will help within 30 days.

Changes to this policy

If the app starts handling data differently, we will update this page and the date below before the change ships.
