Privacy at a glance
Your data stays yours
- No account. No ads.
- Tools run on your phone. What you type, paste or pick in a tool is not sent to our servers.
- The app shows the ToolsServer.com website, so the website’s analytics apply.
Is the app the same as the website?
Yes. The app shows ToolsServer.com (opens in a new tab), so you get the same tools. New tools appear in the app automatically, without an update.
Do I need an account?
No. Open the app and pick a tool.
What happens to files I use in a tool?
They stay on your phone. Tools run on your device, so what you type, paste or pick is not uploaded to our servers. See the privacy policy.
Does it work offline?
Tools you have opened before keep working offline. A tool you haven’t opened yet needs an internet connection the first time.
Where are my downloads saved?
In your phone’s Downloads folder.
A tool gave me a wrong result.
