Terms & Refunds

Effective: August 2026 · Tidemill / Heron Networks LLC

The Short Version

Everything on Tidemill is free to use. Pro is one optional payment of $12 that adds encrypted backup and restore across every tool. There is no subscription and nothing recurring — we cannot charge you again, because we do not store a payment method. If you want your money back within 30 days, email us and you get it, no questions and no forms.

What You Are Buying

Tidemill Pro unlocks encrypted backup and restore in every Tidemill browser tool. It encrypts the data those tools have stored on your device under a passphrase you choose and gives you the file. Your purchase is for that capability, on the tools as they exist today. New tools we add are included at no extra cost.

What Stays Free

All of the tools, in full, permanently. Pro is additive. We will not take a feature that is free today and put it behind Pro later — if we ever need to charge for something new, it will be something new.

Refunds

Email support@tidemill.io within 30 days of your purchase and we will refund it in full. You do not need to explain why, and you do not need to return or delete anything. Refunds go back to the card you paid with and usually appear within 5–10 business days, depending on your bank. If you paid through Apple or Google in a mobile app, their refund process applies instead, because they hold that transaction, not us.

Your License Key

Because Tidemill has no accounts, your license key is your receipt. It is a signed token containing the email address you paid with. Keep it — pasting it into the Pro page is how you restore Pro on a new browser or machine. If you lose it, email support@tidemill.io from the address you purchased with and we will reissue it. The key is for your own use; please do not publish or resell it.

Payment Handling

Payments are processed by Stripe. We never see or store your card details. The only thing we receive is the email address Stripe collects, and it lives inside your license key rather than in any database, because we do not operate one.

What We Do Not Promise

The tools are provided as they are. We think they work well and we use them, but we cannot promise they are correct for every purpose — several of them do measurement, structural, financial, or health-adjacent calculations, and you should not treat any of them as a substitute for professional judgement where that matters. Your data lives on your device, so it is also your responsibility to keep a backup, which is precisely what Pro is for. If a passphrase is lost, an encrypted backup cannot be recovered by anyone, including us.

Changes

If these terms change, the version in effect when you purchased is the one that applies to your purchase. We will not apply a later change retroactively to something you already paid for.
