Numbers Plain calculates dates, names, and number sequences in the current browser page. Tool inputs and results are not added to URLs, browser storage, analytics events, email, or discovery files.
What we collect
The date, name, and sequence you type are read only by the local calculator code and are never transmitted to Numbers Plain. There is no account or login.
Analytics
Pages load our self-hosted Umami service. Umami's current tracker documentation says it uses no cookies, no cross-site tracking, and no personal-data collection. Numbers Plain sends only the property-free events work_started and work_completed; neither event includes a date, name, sequence, calculated number, result text, or user identifier.
Advertising
The current build reserves advertising space, but every ad-unit identifier is empty, so its lazy loader does not request the AdSense library. Tool inputs and results are outside every advertising attribute and event.
Google's current publisher requirements require a Google-certified consent platform integrated with the IAB Transparency and Consent Framework when serving personalised AdSense ads in the EEA, United Kingdom, or Switzerland. Any later activation must preserve that consent surface.
