Privacy Policy
Short version: what you write in Headwork stays on your device. We have no accounts, no advertising, no tracking cookies and no way to read your drafts, attempts or journal.
Last updated 13 November 2026.
What stays on your device
The think pad, writing pad, coach setup and self-check run in your browser. They store the following in your browser's own storage, on your device only:
- Your settings and theme.
- Daily counts from the think pad: how many asks, how many with an attempt first, how many in coach mode, and which AI you tapped. The questions themselves are not kept, apart from an unsent draft so a reload does not lose your typing.
- Journal lines you choose to save.
- Writing pad drafts and their record of how the text was produced (what was typed or pasted, and when).
- Your licence key and trial start date, if any.
The self-check stores nothing: your answers are gone when you close the page.
You can export or delete all of it at any time from Settings in the think pad or writing pad. Clearing your browser data also removes it. Because we do not have a copy, we cannot restore it for you.
What leaves your device
- The prompt you send to an AI. When you tap an AI button, your question and attempt are copied to your clipboard and the AI's website opens (for Perplexity, the text is passed in the link). That text goes to the AI company you chose, under their privacy policy. It never passes through our servers.
- A licence key check. If you activate Pro, your browser sends the key to our server to confirm it is valid. Nothing you have written is sent with it.
- Anything you choose to share. For example a proof-of-process file you download and send to a teacher, or a result card you share. You decide who gets it.
- Email you send us. If you write to us or join an early-access list, we keep your email address to reply, and delete it when you ask.
The browser extension
- Where it runs. Only on chatgpt.com, claude.ai, gemini.google.com, copilot.microsoft.com (and copilot.com, where Copilot sends you once you sign in) and perplexity.ai. It asks for no access to any other site.
- What it reads. The text in the message box, at the moment you press Send, so the card can show your question back to you. It is held in memory while the card is open and then dropped. It does not read the AI's answers.
- What it keeps, in your browser only. Your settings, and one row of counts per day: how many asks, how many you tried first, and on which AI site. If you set a lock code, only a salted hash of it.
- What it sends to us. Nothing on the free plan. With a Pro key, a random install number and the key go to our licence service once a day to confirm the key is valid.
- What it adds to your message. Your own attempt and, if you choose it, one line asking the AI to coach you. The full text appears in the chat exactly as it was sent, so nothing is added out of your sight.
What Headwork does not do
- No accounts and no sign-in.
- No advertising and no selling or sharing of personal data.
- No tracking cookies and no fingerprinting.
- No reading of AI answers or of your chats with any AI.
- No monitoring of children or anyone else.
Payments
Payments are handled by Paddle.com, our merchant of record. Paddle collects your payment details, email and billing country to process the order and handle tax. We receive your email, order details and country from Paddle so we can issue your licence and help with support. We never see your card number. See Paddle's privacy policy.
This website
The site is served by Cloudflare. We use Cloudflare Web Analytics, which counts page views without cookies and without identifying you. We also keep a few plain counters of our own, such as how many times a price button was pressed in a month. Each is a single number: no cookie, no ID, and nothing about who pressed it. Fonts are loaded from Google Fonts, which means your browser requests them from Google's servers. Like any web server, ours processes your IP address to deliver pages; we do not use it to profile you.
Children
Headwork is not directed at children under 13, and we do not knowingly collect personal data from them. The AI services it links to have their own age rules: ChatGPT and Perplexity are for 13 and up, and Claude is for 18 and up.
Changes
If this policy changes in a way that matters, we will say so on this page and change the date at the top.
