Privacy · Zero tracking
Privacy Policy
Free timers collect nothing. Your settings stay on your device. If you buy Pro, payment data goes to Polar — never to us.
Last updated: September 2026
We collect
Nothing directly
No accounts, no first-party tracking cookies, no activity logs.
On your device
Prefs stay local
Theme, sound, and presets live in your browser localStorage.
With Polar
Purchase data only
Email, billing, and order data are processed by Polar as Merchant of Record.
Data Collection
We collect zero personally identifiable information directly. CleanStopwatch requires no accounts, sets no first-party tracking cookies, and does not log what you time.
When pages and embeds load, Cloudflare records standard anonymous network metrics such as IP address, user agent, and referrer to prevent abuse and measure aggregate usage. These logs are not sold, shared, or used for profiling.
Local Storage
Timer preferences such as theme, accent color, sound, duration, and presets are saved in your browser localStorage. This data never leaves your device unless you explicitly sync presets with a Pro license key.
If you enter a Pro license key, the key and its activation status are stored locally to unlock premium features. Validation happens against Polar servers and only transmits the key itself — never payment details. Clearing site data removes local prefs and requires re-entering your key.
Third-Party Services
CleanStopwatch uses the following processors, each governed by its own policy:
- Cloudflare — CDN, DNS, and security
- Google AdSense — advertising on free pages
- Polar — checkout, subscriptions, invoicing, refunds, and license keys as Merchant of Record
- Stripe via Polar — underlying card payment processing
Payments via Polar: what goes where
Polar acts as reseller for Pro purchases. That means Polar — not us — is the merchant on your receipt and handles VAT, GST, and US sales tax, compliant invoices and receipts, refunds, and chargebacks.
| Data | Who processes it | Why |
|---|---|---|
| Email, name, billing address | Polar | Orders, receipts, support |
| Card type, last 4 digits | Polar via Stripe | Payment only — full numbers never touch us |
| Business name, Tax ID, VAT status | Polar | Correct tax rate and reverse charge |
| IP and location at checkout | Polar | Tax calculation and fraud prevention |
| Purchase history, invoices | Polar Customer Portal | Self-serve receipts and cancellations |
We store nothing payment-related:no card numbers, no billing addresses, no tax IDs on our servers. For billing privacy requests such as access or deletion of order data, contact Polar directly — we have nothing to delete. See Polar Privacy Policy, Polar Buyer Terms, and Stripe Privacy Policy.
Your Rights
Depending on your jurisdiction, including under GDPR and CCPA, you may have the right to access, correct, delete, restrict, or port your personal data and to object to certain processing.
How do I exercise these rights?
- For timer use: there is nothing stored server-side to access or delete. Clear your browser site data to remove local prefs.
- For Pro purchases: contact Polar via its Customer Portal or support@polar.sh for invoices, order data, and tax records.
- For ads: manage personalization in Google Ad Settings.
- For anything else: email support@cleanstopwatch.com and we will point you to the right processor.
Contact
CleanStopwatch is operated by an independent solo developer. Product and privacy questions: support@cleanstopwatch.com. Billing, invoice, and refund questions for Pro orders are handled fastest inside the Polar Customer Portal or at support@polar.sh — include your purchase email. The service itself is usable by anyone; purchasing a Pro subscription requires you to be 18 or older, or to have parent or guardian consent.
