How long Charles Read keeps each kind of data about the people who use Setenta. Setenta has no accounts, so there is no account data to keep or to delete.
| Data | Kept for |
|---|---|
| Your settings: the appearance, the language, which language the numbers are said in and from which country (Spanish from Spain or Mexico, Portuguese from Brazil or Portugal, Italian from Italy, French from France or Quebec, English from the United States or the United Kingdom, German from Germany or Austria, Catalan from Catalonia, Chinese from mainland China or Taiwan, Japanese from Japan, or Korean from South Korea), the voice you chose, the kinds of number you want to practise, whether new numbers play by themselves, whether a right answer moves on by itself and which hand the keypad is for | On your device, until you uninstall the app or, in a web browser, clear this site's data, and in any backup of your device you keep. We never receive it |
| Your progress, kept separately for each language you practise: whether each answer was right or wrong (never what you typed), your level for each kind of number, which similar-sounding numbers you have confused, how often you have written a number with its digits swapped, a number backwards, or a time an hour late, and the days you practised | On your device, until you uninstall the app or, in a web browser, clear this site's data, and in any backup of your device you keep. We never receive it. You can also erase your progress in the app, one language at a time: the reset button at the bottom of the Progress screen erases the progress of the language you are practising and keeps the rest |
| Server logs: the IP address of every request | Until overwritten. The log is limited by size, to 21 MB, not by date; that comes to at most about 6 days, and less when the service is busier. A copy of the server replaced by an update keeps its log until a daily clean-up removes it a week after it started, so each line is deleted within 8 days of being written, and a day longer for each daily clean-up missed while the server was down |
Web server logs: the IP address, the time, the host name and path requested (without anything
after a ?), the response status, its size and how long it took |
It is rotated daily, and a line is deleted within 8 days of being written. Before 2026-09-18 it recorded the full address of each request, the page you came from and your browser's identification; since that day those older logs are rotated daily too, and all of them are deleted by 2026-10-03. |
| Crash reports and statistics from the App Store or Google Play | As long as Apple and Google keep them in the consoles they give us; they carry nothing we can link to you |
| Messages you send us, and the address you send them from, in the mailbox Google hosts for us | As long as we need them to answer you and deal with what you raised, or until you ask us to delete them |
Our logs are not rewritten on request; each line is deleted on the schedule above.
