Privacy policy

Last updated 2026-11-02

This policy covers the website plungelog.app, run by Viral Labs. The PlungeLog app will have its own policy when it launches.

The short version

• The cold plunge time calculator and the contrast therapy builder run in your browser. The temperatures, minutes and settings you enter are never uploaded or stored by us. A "copy a link" button puts your settings in the link you copy, and nowhere else.
• If you join the early-access list, we store your email address and a few details about the sign-up so we can email you about the launch.
• We use Google Analytics and Microsoft Clarity to understand how the site is used. Anything you type into a form is masked in Clarity.
• We never sell your data, and we never collect health data on this site.

The early-access list

When you submit the early-access form, we store your email address, the page and spot you signed up from, the date, your country (from your connection) and the device type. We keep it on Cloudflare's infrastructure. We use it only to email you about the PlungeLog app and new tools, at most a handful of times, and each email will include a way to unsubscribe. To have your email removed at any time, write to viral.b.tandel@gmail.com.

Analytics

Google Analytics 4 records anonymous usage such as pages viewed, tools used (for example that a calculation was run and which temperature band it landed in, never your identity) and whether the early-access form was submitted. Microsoft Clarity records how pages are used (clicks, scrolls, taps), with anything typed into forms masked. Both load only after you interact with a page. You can block them with any standard tracker blocker without losing any feature of the site.

Cookies

The analytics tools above set cookies to recognize a returning browser. The site itself does not need cookies to work.

Children

The site is for adults who use cold plunges and saunas. We do not knowingly collect email addresses from children under 13. If you believe a child has signed up, email us and we will delete it.

Changes

If this policy changes, the date at the top changes with it.
