In short

The app does not collect, transmit, sell or share any personal data. It has no account, no ads, no analytics, no tracking and no internet permission on Android. Everything you enter stays on your phone.

What the app stores on your phone

Projects (name, client, site, notes), circuits, saved calculations, the history of recent calculations (the last 100), the cable tables you type or import, your settings, and, if you enter them, your company name, address, phone number, e-mail address, registration number and logo for the PDF header. This data is in the app's private storage on your phone. Deleting a project, a table or the app removes it. A restore replaces it with the content of the backup file you choose, after the app has kept one copy of the data that was there.

Permissions

The app asks for no permission. Files you choose (a backup, a table in CSV format, a logo) come through the system file picker, which hands the app only the file you pick.

How a PDF or a file is made and shared

PDF reports are made on your phone by the phone's own print system from the data in the app. Spreadsheet (CSV) files and backup files are made on your phone. A file leaves the phone only when you choose a place for it in the system share sheet (for example mail, a messenger or a cloud folder). From then on the receiving app's or service's rules apply, not this policy. The backup file is readable text and is not encrypted: it contains your customers' names and addresses if you entered them. Keep it somewhere safe.

Links

The "Sources" screen has buttons that open public web pages (for example encyclopaedia and technical articles). Tapping one opens the page in your phone's browser view; that website then sees your visit under its own policy. The app does not send any data with the link and does not open any link by itself.

Calculations, results and your responsibility

Calculations run on your phone. The app is a calculation aid; the results are not a design approval or a certificate, and you are responsible for checking them against the rules that apply to your installation.

Phone backups and the stores

On iPhone, the app's data is part of your normal iPhone backup (iCloud or a computer) like the data of any app; that is done by the phone, not by the app. On Android, the app switches the phone's automatic app backup off. Apple and Google may give developers anonymous crash or usage statistics if you allowed this in your phone's settings; the app itself contains no code that creates or sends such reports.

Children, ads, sharing of data

The app is meant for people at work in electrical installation, not for children. It has no ads and no purchases (version 1). No data is shared with anyone.

Your rights

Because the developer holds no data about you, there is nothing to request from the developer: you can see, change, export and delete all your data in the app. If you write to the contact address, only the e-mail you send is processed, to answer you.

Changes

If a later version changes how data is handled, this page and the app's About screen will say so before that version is published.
