Privacy Policy — Plain and Simple Tools

Last updated: August 8, 2026

Plain and Simple Tools is a container app that holds small tools, each doing one thing. It has no way to reach the internet at all — not for updates, not for content, not for anything. That is checked by a test that fails the build if any code capable of making a network request appears in any part of the app.

Nothing you do in it is recorded, counted, or sent anywhere.

Permissions belong to the tools, not to the app

The shell — the shelf, the tab bar, Settings — asks for nothing. A tool declares what it will ask you for, and the shelf shows you that on the card before you tap it. A tool you have never opened is never even started, so it can never ask for anything.

Two tests read the app's own source code and fail the build if that stops being true: one if permission code appears anywhere outside a tool's own folder, and one if the app declares a permission that no tool asked for. The second is what permanently keeps full photo-library access out of the app.

Today, two tools ship and between them they ask for two things.

What the app accesses

• The camera — the Negatives tool only. To look at a film negative and turn it into a photograph. The camera is on only while Negatives is the screen you are looking at, and is stopped as soon as you leave it. The conversion happens on your phone. Nothing is recorded or kept, and no image is sent anywhere.
• Your photo library, add-only — the Negatives tool only. When it saves a photograph it has made, it uses iOS's add-only permission. That lets it put pictures into your library and never lets it see one that is already there. It is the least the app could ask for; the cost is that it cannot file its own results into an album of their own, and that was accepted rather than asking for more.

The Charge tool asks for nothing at all. It reads the battery level that iOS already publishes to any app.

The app does not access your contacts, your location, your microphone, your health data, or your photo library for reading.

Data the developer collects

None, and there is no mechanism by which any could be collected. There is:

• No account or sign-in.
• No analytics or tracking of any kind — nothing counts which tools you open.
• No third-party servers, SDKs, or advertising networks.
• No network requests at all.
• No ads, no purchases, no subscription.
• Nothing downloaded after you install it.

The app is declared as "Data Not Collected" on its App Store privacy label.

Data storage and deletion

Everything the app keeps is stored on your device: which tools you have pinned to the tab bar, and the last charger Charge measured, so the Lock Screen tile has something to show. Deleting the app removes all of it.

Photographs made by the Negatives tool are saved into your own photo library and are yours from the moment they land — the app cannot see them afterwards, or delete them.

Children's privacy

The app collects no data from anyone. It is not directed at children and gathers no personal information.
