The rules every app follows
- No ads, no sale, no third-party analytics. We do not sell or share your data. No app has an advertising or analytics library.
- Usage data, on by default, with a switch. Each app sends counts and timings: what was used, for how long, and what went wrong. You can turn it off in the app's settings. Off, nothing more is sent.
- One random code, kept one year. Usage data carries a random code made on your device, so we can tell one player or device from another in totals. It is not your name and is not linked to an account, phone number or advertising id. We remove the code from everything we keep one year after the event it came with.
- No IP address kept. Our server sees your IP address to answer, as every server does. We never store it. We keep at most your country, which Cloudflare reads from it.
- Used only to make the apps work better. We look at totals across all players: which boards are too hard, what crashes, what is slow. We never use it to profile, advertise to or contact anyone.
- Our servers. Data goes to our own Cloudflare account (Cloudflare stores it for us as a service provider) and to our own computer for analysis. No one else gets it.
How long we keep it (our written retention policy)
- The files our apps upload, as sent: 30 days, while we check and convert them. Then only the converted events are kept.
- Usage events, without the random code: kept for good, to compare versions over the years. With no code, an event cannot be tied to anyone.
- The random code on those events: one year after the event, then removed from every copy. It lets us count players and devices within a year. Our tools remove it automatically, and fail if they find one older.
- Your IP address: never stored.
Children
Our apps are for children too. We collect usage data from children only to make the apps work and work better. It holds no name, no contact details and no location finer than the country, and its code is removed after one year. We never ask a child for contact details. A parent can turn usage data off in each app, and can write to us at any time.
What Isopix sends, and what it keeps
- Sent to us, while Share play data is on (at the bottom of Settings; on to start with), from isopix.app only and never from automated browsers:
- How Isopix is used: when it opens, with the window size and display settings; which screens, dialogs, buttons, tools and keys are used, never where on the screen; when a drawing is started, finished or left; settings changed from and to, never the colours you pick; how long a visit lasts; how fast it loads and slow moments.
- The kind of device: screen size, touch or not, installed or not, light or dark, reduced motion, and language.
- What went wrong: the kind of error and where in the app, never its message.
- With each record: the device's random code, which never changes, and the country the visit came from.
- Not sent: your drawings, their names, anything you type, your city or region, or your browser's full identifying string. Your drawings stay in your browser.
- Cloudflare, our host, also counts page views, without cookies.
Deleting your data
- In your browser: clear isopix.app's site data. That deletes your drawings too, so export any you want to keep first.
- Usage data: turn Share play data off to stop sending more. We can't tell which records are yours: the code is never shown and is linked to nothing else. It is removed after one year anyway.
