Terms of use
The plain terms.
These terms cover buying and using Glassmail and using this website. They’re written to be read, not skimmed past.
Last updated 13 November 2026
1. Who these terms are between
These terms are between you and the maker of Glassmail (“we”, “us”). Glassmail is sold through Polar, which is the merchant of record for every purchase: Polar processes the payment, charges any sales tax or VAT, and issues your receipt, underPolar’s own terms. By buying or using Glassmail, you agree to these terms.
2. Your licence
- A Glassmail licence is a one-time purchase. It never expires and there is no subscription.
- One licence is for one person and works on up to three Macs that person uses. You can free up a Mac in the app or in the customer portal and use the licence on another.
- It includes every version 1 update (1.x). A future version 2, if there is one, may be a separate, optional paid upgrade; version 1 keeps working either way.
- The licence lets you use Glassmail. It doesn’t transfer ownership of the software. Don’t share, resell or publish your licence key, and don’t try to get around the licence check.
3. The free trial
Glassmail is free to use for 14 days with every feature. After that it asks for a licence to keep working fully. Your mail stays on your Mac and with your provider whether or not you buy.
4. Prices and refunds
Prices are shown on this website and at checkout, in US dollars unless checkout shows otherwise. Launch prices rise as licences sell; the price you pay is the price shown at checkout. You can get a full refund within 14 days of buying, with no questions asked. See therefund policy.
5. Your accounts and your mail
You’re responsible for the email accounts you connect and for what you send. Glassmail connects to your provider on your behalf, so your provider’s own terms still apply to your account. Keep your own backups of anything important: your provider keeps your mail, and Glassmail keeps a copy on your Mac, but we can’t recover mail that you or your provider delete.
6. AI features
AI summaries, drafts and answers are generated on your Mac and can be incomplete or wrong. Read them before you rely on them, and always check a draft before you send it. Glassmail never sends a message without you pressing Send. If you connect an outside AI agent, that agent’s terms and privacy policy apply to it.
7. Acceptable use
Don’t use Glassmail to send spam, to break the law, or to access accounts you aren’t allowed to access.
8. Updates and support
We work to keep Glassmail working with the providers it supports and fix problems promptly, and we answer support email. Email providers change things outside our control, so we can’t promise every feature will work with every account forever.
9. No warranty
Glassmail is provided “as is”. To the extent the law allows, we don’t make promises beyond those in these terms, including that it will be error-free or uninterrupted. This doesn’t affect rights you have as a consumer that can’t be excluded.
10. Limits on liability
To the extent the law allows, we aren’t liable for indirect or consequential losses, or for lost data, and our total liability to you is limited to what you paid for Glassmail. Nothing in these terms limits liability that can’t be limited by law.
11. Ending
You can stop using Glassmail at any time. If you seriously break these terms (for example by sharing or reselling your licence key), we may revoke the licence.
12. Changes to these terms
We may update these terms. The date at the top shows the latest version. Changes don’t take away a licence you’ve already bought.
