Terms of Service

Effective 20 October 2026

These terms cover Guardpup's browser extension, Mac app and developer tool, free and paid. We've kept them short and plain. By installing or buying Guardpup, you agree to them.

Who We Are

Guardpup is made by Donmac, a sole proprietorship registered in the Republic of Korea ("we", "us"). Contact: hello@guardpup.io, or the contact form.

What Guardpup Does, and What It Can't Promise

Guardpup checks what you send to supported AI services, on your own device, and helps you keep passwords, keys and personal details out of them. It lowers the chance of a leak. It can't catch everything: no detector is perfect, AI services change their pages, and you can choose to send something anyway.

You remain responsible for what you share and with whom. If a secret has been exposed, change it; Guardpup doesn't replace that. Guardpup is not affiliated with OpenAI, Anthropic, Google or any other AI provider; their names belong to them.

Using Guardpup

• Free. Anyone may use the free product, personally or at work, at no charge and without an account.
• Pro. Pro features (such as screenshots and files, your own protected items and the weekly report) need a Pro subscription, paid monthly or yearly, for one person.
• Team. Company features (company rules, company lists of things to protect, and installing for everyone) need a Team subscription, paid monthly or yearly for each person who uses them. It includes Pro for each of those people.
• Accounts. Pro and Team need a Guardpup account. Keep your sign-in to yourself and give us an email address that works. You're responsible for what happens under your account.
• A subscription or licence is for the person or company named in it. Don't share it with anyone else, and don't alter or work around the subscription or licence check.
• You may inspect how Guardpup works. If you find a security problem, please tell us (see security) rather than publishing it first.
• Guardpup belongs to us: using it doesn't make any of it yours. Don't copy, change, resell or redistribute it, take it apart beyond what the law allows, or use it to build a competing product.
• Don't use Guardpup to break the law or the terms of the AI services you use.

Paid Plans

Paid plans are sold by our reseller, Lemon Squeezy, which acts as the merchant of record: it takes the payment, charges any sales tax or VAT, and issues your invoice. Its buyer terms apply to the purchase itself.

• Pro is billed monthly or yearly; Team is billed monthly or yearly, per person, for at least 3 people.
• Plans renew automatically each month or each year, depending on the plan you chose, until you cancel. You can cancel any time from the link in your receipt; the plan stays active until the end of the period you paid for.
• The Pro free trial lasts 7 days and needs no card. Team trials last 14 days, are free and need no card. We don't charge you when a trial ends: paid features simply switch off unless you subscribe.
• Prices may change; we'll tell you at least 30 days before a renewal at a new price.
• Refunds: see the refund policy.
• Team seats: buy for the number of people your company rules apply to, and update it as your team changes.

If a paid plan ends, its paid features switch off and the free product keeps working. We never stop basic protection because someone, or their employer, stopped paying.

Your Data

What you check with Guardpup stays on your device. The privacy policy explains what Guardpup stores locally and the little we receive: for Pro and Team, your account (email, plan, team and connected apps); billing details come from our reseller. Never what you type, paste or attach.

Updates and Changes

We update Guardpup to keep up with AI services and to fix problems; updates arrive through the Chrome Web Store and similar stores. We may change or stop a feature. If we ever stop the paid service, we'll refund the unused part of any prepaid period.

We may update these terms. We'll change the date above, and tell paying customers by email at least 30 days before a change that affects them takes effect.

Warranty and Liability

Guardpup is provided "as is". As far as the law allows, we make no promises beyond those in these terms, including that it will catch every secret or work with every service.

As far as the law allows, we aren't liable for indirect or consequential losses, such as lost profits, lost data or the cost of a leak, and our total liability for any claim is limited to what you paid us in the 12 months before it (or US$50 if you've paid nothing). Nothing here limits liability that can't be limited by law, or your rights as a consumer where you live.

Ending

You can stop using Guardpup any time by uninstalling it. We won't renew a licence that's been shared or tampered with, and will tell you why.

Law

These terms are governed by the laws of the Republic of Korea, and the Seoul Central District Court has jurisdiction, except where your local consumer law gives you the right to use your own courts.
