Privacy Policy

Last updated 2026-11-07

This Privacy Policy explains what information the operator of the Steady Zero website (steadyzero.com) (“we,” “us”) collects through steadyzero.com (the “Site”), how we use it, and the choices you have. It is written to meet the California Online Privacy Protection Act (CalOPPA, Cal. Bus. & Prof. Code §§ 22575 to 22579) and applies to visitors everywhere.

1. The short version

Calculator numbers stay in your browser. Your calculator inputs never leave your browser, unless you choose to share a results link. Our calculators run on your device. The balances, rates and payments you type are not sent to us. If a calculator offers to remember your inputs, they are saved only in your browser’s local storage, and you can clear them at any time.
No ads, no tracking cookies, no data sales. We don’t use Google Analytics, advertising pixels or cross-site tracking, and we never sell or share personal information for advertising.
We collect personal information only when you give it to us: when you buy a template, look up your download links or email us.
We don’t run an email list. We don’t collect email addresses for marketing, and we don’t send marketing email.

2. Information we collect

Purchases. Checkout is run by Link (Sold through Link, LLC, a Stripe company), the merchant of record. You give your payment details to Link and Stripe, not to us; we never see or store your full card number. After a purchase, Stripe and Link send us order records: your email address, name and billing country, the product, the amount, tax, currency, the payment and checkout reference numbers, and the order status (for example, refunded or disputed). We store an order record with an order number so we can deliver your files and help you recover them.

Download recovery. When you use the downloads page, you enter your order number and purchase email. We use them only to find your order. We keep short-lived counters of attempts (by email and by your IP address) to limit abuse.

Sharing your results. The “Email me my results” link opens your own email app with a link to your calculation already filled in. The link contains the numbers you entered, so only send it to people you trust. Nothing is sent to or stored by us. “Copy link” works the same way.

Messages to support. If you email support@steadyzero.com, we receive your email address and whatever you include in your message.

Analytics. We use Cloudflare Web Analytics, which is cookieless: it does not store anything in your browser, does not use your IP address to identify you and does not fingerprint visitors. It gives us aggregate counts such as page views and referring sites.

Server logs. Our hosting provider (Cloudflare) processes technical information such as IP address, browser type and request time to deliver and protect the Site. We don’t use it to identify visitors.

3. How we use information

We use information to deliver your purchases and download links, provide support, process refunds and withdrawals, prevent fraud and abuse, keep records we are legally required to keep, understand overall Site usage, and keep the Site secure. We don’t send marketing email.

We share information only with service providers that help us run the Site, and only as needed:

Stripe and Link (payments, receipts, refunds, tax, fraud prevention). Link acts as merchant of record and handles buyer data under its own privacy policy: https://link.com/privacy. Stripe’s privacy policy: https://stripe.com/privacy.
Cloudflare (hosting, storage of order records and files, cookieless analytics): https://www.cloudflare.com/privacypolicy/.

We may also disclose information if the law requires it, to protect our rights or the safety of others, or as part of a sale or transfer of the business. We do not sell personal information, and we do not “share” it for cross-context behavioral advertising.

5. Cookies and Do Not Track

The Site does not set advertising or analytics cookies. Stripe’s checkout pages, which are run by Stripe and Link, may set their own cookies for security and fraud prevention.

Do Not Track: because we don’t track visitors across other sites or over time for advertising, the Site responds to browser “Do Not Track” signals and Global Privacy Control the same way it treats every visitor: with no cross-site tracking. We don’t allow third parties to collect personal information about your online activities over time and across different websites through our Site for advertising. Stripe’s and Link’s checkout pages follow their own privacy policies.

6. How long we keep information

Order records: as long as needed to deliver your files and for tax and accounting records (generally up to 7 years). Support emails: as long as needed to resolve your request. Rate-limit counters: minutes to hours. Backups follow the same periods.

7. Your choices and rights

Review, correct or delete: email support@steadyzero.com from the email address on your order. We will respond within 30 days. Some order data must be kept for legal and tax reasons.
Payment data held by Link/Stripe: contact Link support, or see Link’s privacy policy.
EU/UK visitors: you may have rights to access, correct, delete, restrict or object to processing, and to complain to your data protection authority. Our legal bases are performing our contract with you (orders), legal obligations (records), and legitimate interests (security, aggregate analytics). You can also ask for a copy of your data in a portable format. We are based in the United States, so your information is processed and stored in the US by us and our service providers.

8. Children

The Site is not directed to children under 13 (or under 16 in the EU/UK), and we don’t knowingly collect their information.

9. Security

We use HTTPS, signed and expiring download links, and access controls on our systems. No method of transmission or storage is completely secure.

10. Changes to this policy

If we change this policy, we will update the “Last updated” date above and post the new version on this page. If a change is material, we will also note it on the home page when it takes effect.
