Sketch Scale Plan turns a page in your sketchbook into an accurate wall plan — true proportions, a real paint list, and a colorway you can test before the first can hisses open.
Drop your scan onto the real wall dimensions and get a chalk-ready grid overlay, cell by cell, at true size.
The app reads the colours off your own drawing and turns coverage into a shopping list of caps — one trip, not three.
Finger-paint a photo of the real surface at true cap width before you commit a single can to the wall.
Log what actually went up. Brick drinks paint, metal doesn't — the app learns your real usage, session after session.
One square fills the screen at a time. Hold to check it off, and the grid keeps your place while your hands are full.
No account, no upload, nothing leaves the phone. Your archive of pieces stays exactly where you left it.
Enter your sketch size and the real wall size. We'll work out the scale factor and how many grid squares you'll be chalking up.
Sketch Scale Plan is built to work entirely on your device. We do not collect, store, or transmit any personal data, and we never see your sketches, your walls, or your paint lists. Here's exactly how that works.
None. We do not collect names, emails, photos, locations, device identifiers, or usage statistics. The app has no sign-up, no login, and no form that sends anything back to us.
There is nothing to use. We do not analyse your sketches, your session logs, or your paint history, and we do not sell, rent, or share information with anyone — because none is ever gathered.
Every scan, scale calculation, colorway test, and session note is written to storage on your own phone. There is no cloud sync, no backend server, and no remote database holding a copy of your archive.
Sketch Scale Plan does not embed third-party analytics, advertising networks, or tracking SDKs. No usage data is passed to any outside company because no such connection exists in the app.
Since your paint lists, photos, and notes never leave the device, they're protected by your phone's own security — screen lock, encryption, and permissions — rather than by any server we would otherwise need to secure.
Sketch Scale Plan does not knowingly or unknowingly collect data from any user, of any age. Because no information is gathered at all, the app poses no data-collection risk to children.
There are no accounts to manage and no servers holding your history. Deleting your archive is as simple as clearing it in-app or uninstalling Sketch Scale Plan, which removes everything permanently.
If our approach ever changes, we'll update this page and adjust the Effective Date above. Continued use of the app after an update means you accept the revised policy.
