Hanzi Sheets
Privacy policy
Last updated: September 2026. Hanzi Sheets is built to be private by design: the worksheet generator runs entirely in your browser, and there is no account system.
What we do NOT collect
- The text or word lists you paste into the generator — they never leave your device.
- Your generated worksheets.
- Your mistake book (错词本) — it lives only in your browser's local storage.
What is stored on your device
| Item | Where | Purpose |
|---|---|---|
| Daily free-quota counter | Browser local storage | Enforce the free plan's daily limit |
| Mistake book | Browser local storage | Let you re-print review sheets of characters you marked |
| Generator options | Browser local storage | Remember your grid/paper/template preferences |
| Pro activation code | Browser local storage | Unlock paid features on this device |
Clearing your browser data removes all of the above. We have no server-side copy to restore from.
Payments
Purchases are processed by our Merchant of Record, Waffo Pancake. When you buy a plan, Waffo collects the information needed to process payment and handle taxes (email, country, billing details, card data). We receive from Waffo only your email address, the plan purchased, and the order status — never your card number. Waffo's own privacy terms apply to the checkout.
Analytics
Cloudflare provides cookie-less aggregate page statistics. Only with your explicit permission, we also use Google Analytics 4 for basic page visits. Google may store analytics cookies and device identifiers and process analytics data. Advertising features and enhanced measurement are disabled. We do not send worksheet text, names, birth information, activation codes, form inputs, URL queries or fragments to Google Analytics. Page titles and referring URLs are omitted or replaced; individual character, list and article paths are grouped. We do not sell personal data.
Declining analytics does not affect the generator or other features. Use Analytics preferences to change your choice or withdraw consent. Withdrawal stops future collection and removes accessible analytics cookies on this website; it does not erase previously collected data. Your choice is stored locally in this browser.
仅在你明确同意后，我们才加载Google Analytics 4进行基本浏览统计；它可能保存统计Cookie及设备标识。 拒绝不影响使用，可在“统计偏好”撤回同意。我们不发送字帖文本、姓名、生日、激活码、表单输入或网址参数；撤回后停止未来采集并清除可访问的统计Cookie，不追溯删除历史数据。
If you email us or join the waitlist, we use your address only to reply and to notify you about the product you asked about. One-click unsubscribe, no third-party sharing.
Children
The Service is designed to be used by parents and teachers preparing materials for children. It requires no personal information from children and collects none.
Your rights & contact
For access, correction, or deletion requests related to purchase records, contact [email protected]. Because worksheet content never reaches our servers, there is generally nothing of yours for us to delete.
