What to include#
Bug reports help us fix things quickly when they name the tool (for example “crypto / HMAC generator”), describe the input you gave and the output you expected, and state your browser and its version. If the tool reported an error message, paste the exact text.
Privacy requests (data, consent, or advertising questions) are handled seriously — note that because every tool runs locally in your browser, we never receive the data you process with them, so requests usually concern the consent banner or advertising cookies. Include the date you first saw the behavior and the page URL.
Content suggestions — a missing utility, a guide topic you would like to read, a translation improvement — are welcome. Naming the category the tool would belong to helps us route it.
About the data flow of this site#
One thing worth restating on a contact page: this site has no backend and no storage. There is no server that could receive, log, or lose the values you type into any tool. Everything you enter is processed by your own browser and stays on your device. The only parties that can set cookies are advertising partners, and only after you accept the consent notice.
