Privacy Policy
This policy explains what information 100tools handles, how it is used, and the practical limits of data retention for this site.
Information we handle
We may process the inputs you submit to run a tool, basic technical logs required to operate the service, and account information when you create or use an authenticated feature.
Some tools operate fully in the browser, while others send data to the server so the requested processing can be completed.
How information is used
Submitted data is used to provide the requested tool output, maintain reliability, prevent abuse, and improve the product.
We do not treat your submitted content as public unless a feature explicitly states that content will be shared.
Cookies and local storage
We use browser storage and cookies for essential product behavior such as theme, language, authentication, and session continuity.
Retention and security
We aim to keep data only for as long as needed to operate the service, debug failures, meet legal obligations, or enforce platform safety.
No internet service can be guaranteed completely secure, so you should avoid submitting secrets or regulated data unless the tool explicitly supports that use case and you accept the risk.
Third-party services
Infrastructure providers, analytics, authentication, or content delivery services may process limited data as part of operating the site.
Their handling of data is governed by their own terms and privacy notices.
