Randatum is an offline-first desktop random-data studio. All computation happens locally on your computer. Privacy is a core design principle of Randatum.
Fully offline · no data collection
Randatum does not collect, receive, or upload any of your data. We operate no server of our own — no network, no uploads. All data generation, import, statistics, and export happen locally on your computer.
Your data
The CSV files you import, the random data you generate, the templates you save, and the run records are all stored on your local device. This data is never sent to the Randatum developer or any third party.
No analytics, no ads, no tracking
Randatum contains no analytics SDKs, no advertising SDKs, and no third-party crash reporting. It does not track you across apps or websites.
Network
Randatum is a fully offline app and needs no network connection for normal use; the app itself makes no outbound network requests. The bundled user manual is served from a local 127.0.0.1 service and never touches the internet. The only case that may involve the network is when you actively tap links such as "Support" or "Privacy Policy", which open the corresponding page in your system browser.
No purchase, no licensing
Randatum is completely free — no subscription, no in-app purchase, no license. There is no purchase or licensing flow, and the app contains no payment-related entry points.
Deleting your data
You can delete imported data, generated results, saved templates, and run records at any time. Uninstalling the app clears all local data.
Children
Randatum is not directed at children under 13 and does not knowingly collect information from children.
Changes
We may update this policy; the "last updated" date above will change accordingly.
