This policy explains what ThermPort (the app) and thermport.com (the website) do with data. The short version: the app keeps everything on your Mac and only goes online when you ask it to, and the website has no analytics and sets no cookies.
The app
ThermPort samples your Mac's sensors (temperature, CPU, memory, fan, GPU, battery, network, disk, power, Wi‑Fi) and stores the live history in memory and a long-term history of one-minute averages in ~/Library/Application Support/ThermPort. Nothing is sent anywhere automatically. There is no analytics, crash reporting, advertising or tracking of any kind.
The app connects to the internet only in these cases, each triggered by you or by a setting you turned on:
License activation and periodic validation. Your license key and a name for this Mac are sent to Lemon Squeezy's license service (api.lemonsqueezy.com) to activate, validate or deactivate the key. Lemon Squeezy's privacy policy applies to that service.
Update check. The app fetches a small version file from thermport.com. Like any web request, this exposes your IP address to our hosting provider (Cloudflare); we do not log or store it.
Feedback. When you send feedback from the app, the message and the optional name and contact details you typed are relayed through our mail service (mail.thermport.com, a Cloudflare Worker using Resend) to our mailbox. We keep it as long as needed to answer you.
Emailed reports. If you turn on auto-email, the report PDF and the recipient address you entered are sent through the same mail service to that address. The address is stored only on your Mac.
Ratings. If you rate ThermPort from the About panel, we receive the stars, your comment, the optional name, the app version, your interface language, whether the copy is licensed, and a random identifier generated on your Mac that is used only to limit ratings to one per day. Your IP address is used for a 24-hour rate limit and then discarded. Ratings we approve are shown publicly on thermport.com with the stars, comment, name (if given) and month. You can ask us to remove yours at any time.
The website
thermport.com is a static site served by Cloudflare, which keeps standard server logs under its own privacy policy. We run no analytics and set no cookies. The page loads approved ratings from reviews.thermport.com; nothing about you is sent in that request beyond the ordinary web request itself.
Purchases
Purchases are handled by Lemon Squeezy as the merchant of record. Lemon Squeezy collects your payment details, billing address and email under its own privacy policy and terms. We receive the order details needed to deliver and support the product: your email address, country, order number and license key. We never see your card number.
Email
Messages sent to sales@, contact@ or feedback@thermport.com are forwarded to our mailbox and kept as long as needed to help you.
Your choices
Deactivate a Mac from Settings → License at any time; this removes the activation from Lemon Squeezy's records.
Clear history from Settings → Report; this deletes the long-term history on your Mac.
Email sales@thermport.com to have a rating or your support correspondence deleted.
Children
ThermPort is not directed to children under 13 and we do not knowingly collect information from them.
Changes
If this policy changes, the new version will be posted here with its effective date.
