DIYCalc

Buy enough. Not far too much.

Help with this app

Choose paint, flooring, tiles, wallpaper, concrete, gravel or decking, enter measurements and units, then inspect the formula, waste allowance and purchase quantity. Check measurements and manufacturer coverage figures before buying materials.

Save named jobs for later and share a readable calculation or full JSON backup. Restore validates a selected backup before replacing local saved jobs; an invalid file leaves them unchanged.

Information on your device

DIYCalc stores named jobs, measurements, unit choices, calculation inputs and timestamps in its local SQLite database. Calculations and backup preparation happen on the device. A full backup includes the saved jobs and settings; it is not an encrypted backup service.

The core workflow works without an internet connection. We do not receive your app content through the app and do not operate a NoCloud server for it. The app has no account registration, advertising, subscription, tracking SDK or third-party behavioural analytics. We do not sell personal information. We cannot access or recover your local app content remotely.

Permissions and sharing

File import uses the operating system picker; exports use the native share sheet. Camera, microphone, contacts, device location and notification access are not required.

A photograph, document or backup you select through a system picker may come from a cloud provider you use. When you choose Share, the operating system passes a copy to your selected destination. Email, messaging, file and cloud-storage services have their own privacy practices. NoCloud does not receive that copy unless you deliberately send it to us, for example by email.

Storage and deletion

Delete saved jobs with the app controls; Undo is available until another save or restore. App-owned export files are removed after normal sharing. Interrupted app export files and supported share-cache files older than one day are pruned on a later startup or export/share.

Removing the app or losing your device can remove your only copy. Device backups and transfers are controlled by your operating system and settings; do not rely on them as a guaranteed recovery mechanism. NoCloud provides no cloud backup or recovery. Deleting app content does not delete source files, exports or backups stored elsewhere. Cleanup runs when the app performs the relevant operation, not continuously while it is closed. Normal file deletion is not a promise of forensic secure erasure.

App stores, support and this website

The store handles purchases and downloads under its own policies and may provide sales statistics or platform diagnostic reports. This is separate from the app’s local processing.

If you email support, we receive the information you choose to send through Gmail. Routine support emails are deleted 12 months after an enquiry closes, except information needed for a continuing dispute or legal obligation. Avoid attaching private photographs, documents or customer records unless necessary. Visiting this website sends request information to its hosting provider, Cloudflare. See website and support privacy for details and provider policies.

Privacy questions and requests

Email ascaidevlabs@gmail.com with the subject “Privacy request” to ask about, access, correct or request deletion of information you sent us. Identify the relevant email conversation without attaching private app content. We may need to confirm that the request comes from the person concerned. For content stored only on your device, use the app’s controls; we cannot retrieve or delete it remotely.
