Terms of Service

Last updated October 24, 2026

1. Agreement

These terms are an agreement between you and Your business legal name ("we", "us") for your use of Pure DNS at puredns.app (the "Service"). By using the Service you agree to these terms and to our Privacy Policy. If you don't agree, please don't use the Service.

2. The Service

Pure DNS provides DNS record lookups, WHOIS lookups, blacklist checks and an email deliverability tester ("Mail Tester"). Much of the information comes from outside sources such as DNS resolvers, domain registries and blacklist operators, which we don't control.

3. Free use

Without a subscription you can run up to 5 checks in any 24-hour period across all tools. The count resets 24 hours after your first check. Checks are counted per browser, per network IP address and per account. We may change the free allowance at any time.

4. Accounts

• You must be at least 16 and give a real email address that you control.
• Keep your password safe. You're responsible for activity on your account. Tell us right away at support@puredns.app if you think someone else has used it.
• An account is for one person. Don't share a Pure DNS Pro account or resell access to the Service.

5. Pure DNS Pro subscription

• Price and billing. Pure DNS Pro costs $4.99 USD per month, plus any taxes that apply, charged in advance through our payment processor, Stripe.
• Automatic renewal. Your subscription renews every month and you'll be charged on the renewal date until you cancel.
• Cancelling. You can cancel any time from your account → Manage billing. You keep unlimited checks until the end of the period you've paid for, and you won't be charged again.
• Refunds. Payments aren't refundable and we don't give credit for part-used months, except where the law requires it. If something went wrong with a charge, email us at support@puredns.app and we'll look into it.
• Price changes. We'll tell you at least 30 days before a price change affects your subscription. You can cancel before it takes effect.
• Failed payments. If a payment fails and can't be collected, your subscription may be cancelled and your account will return to the free allowance.

6. Acceptable use

You agree not to:

• use scripts, bots or other automated means to send queries, or scrape or bulk-download data from the Service;
• try to get around the free limit, for example with multiple accounts, rotating IP addresses or clearing cookies to reset counts;
• overload, attack, probe or interfere with the Service or the outside services it relies on;
• send the Mail Tester malware or illegal content, or use it to develop, test or improve unsolicited bulk email (spam) or phishing;
• send the Mail Tester messages you aren't authorized to send, such as other people's private emails;
• use WHOIS or other results to send spam, harass anyone, or breach a registry's or data provider's terms;
• break any law, or help anyone else do any of the above.

7. Your content

Messages you send to the Mail Tester stay yours. You give us permission to receive, store, analyse and display them as needed to provide your results. Results can be viewed by anyone who has their link, and we delete them after 30 days.

8. Results are for information only

The Service and all results are provided "as is" and "as available". Results can be incomplete, out of date or wrong: DNS changes take time to spread, WHOIS data is often hidden or inaccurate, blacklists change constantly, and every mail provider filters differently. A good Mail Tester score doesn't guarantee inbox delivery. To the fullest extent the law allows, we make no warranties of any kind, including fitness for a particular purpose, accuracy or uninterrupted availability.

9. Limitation of liability

To the fullest extent the law allows, we aren't liable for any indirect, incidental, special or consequential damages, or for lost profits, revenue, data or business opportunities, arising from your use of the Service. Our total liability for any claim relating to the Service is limited to the greater of (a) the amount you paid us in the 12 months before the claim and (b) USD $50. Some places don't allow these limits, so they may not fully apply to you.

10. Indemnity

If you break these terms or the law while using the Service and someone makes a claim against us because of it, you agree to cover the costs and losses that result, including reasonable legal fees.

11. Suspension and termination

You can stop using the Service and ask us to delete your account at any time. We may suspend or close accounts that break these terms or put the Service or others at risk. If we close a paid account for reasons other than a breach of these terms, we'll refund the unused part of the current month. We may change or discontinue features. If we shut down the Service entirely, we'll cancel subscriptions and refund any unused paid time.

12. Changes to these terms

We may update these terms. We'll change the date at the top, and for significant changes we'll let signed-up users know by email or on the site before they take effect. If you keep using the Service after that, you accept the new terms.

13. Governing law

These terms are governed by the laws of the Province of Ontario, Canada and the federal laws of Canada that apply there. The courts in Toronto, Ontario handle any dispute, except where your local consumer law gives you the right to bring a claim where you live. Nothing in these terms takes away rights you have under consumer protection laws.
