Privacy

These pages use the Meta Pixel. Every page except the review form runs Meta's pixel, a small script from Facebook that tells Meta the page was visited, so I can measure and target ads on Facebook and Instagram. Meta receives the page's address, your browser's details and your IP address, and may link the visit to your Facebook or Instagram account if you are logged in. The script also sets a cookie on this site (_fbp). Meta handles this data under its own privacy policy. Any content blocker stops the pixel, and you can turn off ads based on it in your Facebook or Instagram ad settings.

Apart from the pixel, the pages load nothing from anyone else: no other analytics, no tag manager, no fonts from anyone else's server, no embedded checkout script. Your browser fetches the page, its fonts and its images from my host.

Buying. Payment is handled by Lemon Squeezy, who are the merchant of record. They take your card details and your email address on their own pages, under their own privacy policy, and I never see your card details. What reaches me is an order reference and the email address they send your receipt to.

Reviewing. If you leave a review, this is everything the review system stores:

What I keep. Your order number, a one-way hash of this link, and what you type. Your email address is used only to send you this link and one reminder five days after you buy, through [email service], and is deleted after that; it is never kept with your review. Once you publish, also the friend code issued for your order, the date it was issued and the id of its discount at Lemon Squeezy — nothing about you is sent to them to make it — kept so your order only ever gets one code (legitimate interests), for as long as I keep your order number. Your connection's IP address is kept as a hash for 24 hours to stop automated submissions, then deleted. Legal basis for publishing: your consent, which you can withdraw any time by emailing me. Data lives in Cloudflare D1 and a private Git repository. Contact: harish@harishsenthilkumar.xyz

The app itself sends nothing anywhere. Your history is a plain text file on your own disk. The one part that can send anything is the optional Google Sheets export, and it stays off until you set it up yourself — and then it writes to a sheet you own, not to me.
