Privacy policy
- Free and Pro: your measurements never leave your browser. We can't see them.
- Buying: our payment provider handles your card. We never see or store card numbers.
- Team and Expert: we store only the projects you choose to save, so they can sync and send reports. Reports are generated automatically; no person reviews your data.
- We don't sell or rent your data, show ads, or track you across other websites.
Who we are
LimitLine is operated by Nicholas Williford, doing business as LimitLine, Kernersville, North Carolina, United States. Questions or requests: [email protected].
What we collect and why
| When | What | Why | Kept for |
|---|---|---|---|
| Using the charts (Free and Pro) | Nothing. Calculations run in your browser; the data you paste or drop stays on your device. | — | — |
| Visiting the site | Standard server logs (IP address, browser type, pages requested) and cookie-free page-view counts. | Keep the site secure and working; see which pages are used. | Logs: as kept by our host, typically short-term. Counts: aggregated only. |
| Buying a license or plan | Name, email, billing country and address, order details. Card details go only to our payment provider. | Process the order, deliver your license key, handle tax, refunds and support. | As long as required for tax and accounting records. |
| Activating a license | Your license key, saved in your browser. Team and Expert keys are re-checked with our payment provider to confirm the subscription is active. | Unlock Pro features you paid for. | Until you remove it from your browser. |
| Joining a waitlist | Your email address. | Tell you when the plan opens. One message, plus updates only if you agree. | Until the plan opens or you ask us to remove it. |
| Team and Expert accounts | Account email, the projects and data links you choose to save, alert and report settings. | Sync your work, refresh charts, send alerts and reports. | While your account is active, then deleted within 30 days of cancellation. |
| Emailing us | Your email and message. | Answer you. | Until the conversation is resolved, then up to 2 years for support history. |
Who we share it with
Only the service providers needed to run LimitLine, each limited to its job:
- Payment provider and merchant of record (Stripe; purchases through Stripe Managed Payments show as "Sold through Link") — checkout, payments, sales tax, receipts and refunds.
- Hosting (Cloudflare) — serving the site and, for Team and Expert, storing saved projects.
- Email delivery — not in use yet. Stripe sends purchase receipts. Before we send any other email, we'll name our email provider here.
We don't sell or rent personal information, and we don't share it for advertising. We may disclose information if required by law.
Tracking and "Do Not Track"
We don't use advertising cookies or cross-site tracking, and we don't allow third parties to track you across other websites through LimitLine. Because we don't track you across sites, browser "Do Not Track" signals don't change how LimitLine works.
Your choices and rights
Email [email protected] to see, correct, export or delete your information, or to stop any emails. We'll answer within 30 days. If you're in the European Economic Area or the UK, you also have the rights to restrict or object to processing, to withdraw consent at any time (for example, for waitlist emails), and to complain to your local data protection authority.
Legal bases (EEA and UK)
Performing our contract with you (orders, licenses, accounts); our legitimate interests in keeping the site secure and understanding aggregate use; and your consent for waitlist and update emails.
Where data is stored
LimitLine is run from the United States, and our providers may process data in the United States and other countries. Where required, transfers rely on the safeguards our providers offer, such as standard contractual clauses.
Security
The site is served only over HTTPS. Saved projects are stored with an access-controlled hosting provider, and access is limited to what's needed to run the service. No system is perfectly secure; tell us right away at [email protected] if you suspect a problem.
Children
LimitLine is not directed to children under 13, and we don't knowingly collect their information.
Changes
If we change this policy in a meaningful way, we'll update the effective date above and, if you have an account or license, email you before the change takes effect.
