The short version. BioLab has no accounts, no signup, and no tracking. Every tool runs in your browser, and what you type into one never leaves your device.
Nothing you type. The tools on this site are plain JavaScript running in your own browser — whatever you paste or enter is processed on your device and is never transmitted to us, never stored, and never seen by anyone else.
We also set no cookies, write nothing to local storage, and load no analytics or other third-party scripts. There is no account to create and nothing to log in to.
This site is served by Cloudflare Pages. Like any web host, Cloudflare logs ordinary request data — IP address, browser user agent, the URL requested, and the time — in order to deliver pages and block abuse. Cloudflare processes this as our hosting provider under its own privacy policy. We do not combine it with anything else and do not use it to identify visitors.
The site is also verified in Google Search Console, which reports aggregate search statistics (which queries showed the site, how many clicks). These are counts, not people — Google does not expose individual visitors to us.
Some pages may offer an email newsletter. If you enter your address in that form, it is sent to Kit (formerly ConvertKit), which stores it solely to deliver the newsletter you asked for. Every email carries an unsubscribe link, and unsubscribing removes you from the list. We do not sell, rent, or share the list.
We link out to third-party tools such as Buffer and Later. Some of those links are or may become
affiliate links — those are marked rel="sponsored" and disclosed on the page itself.
If you follow one, the destination may set its own cookies to credit the referral. Once you leave
this site you are covered by that company's privacy policy, not ours.
Because we hold no personal data, there is normally nothing for us to look up, export, or delete on request. The one exception is the email list: if you are on it and want your address removed, use the unsubscribe link in any email or write to us at the address below and we will remove it.
These tools are aimed at working professionals and are not directed at children under 13. We knowingly collect no personal data from anyone, children included.
If any of the above changes, we will update this page and the date at the top of it.
