mug Terms of Service

Effective date: November 3, 2026

These terms are an agreement between you and SCHELL CONSULTORIA PALESTRA E EVENTOS LTDA, a Brazilian company (CNPJ 49.241.699/0001-70) (“mug”, “we”, “us”), for the mug macOS app, the server behind it and getmug.dev (the “Service”). By activating a license or using the Service you agree to these terms and our Privacy Policy.

If you are in Brazil, the Portuguese-language rights under LGPD apply; contact us in Portuguese if you prefer.

1. The Service

mug turns links, notes and files you save into reusable coding guidance (“patterns”) and offers the patterns you approve to coding agents you connect, such as Codex and Claude Code. Your library is stored on your Mac. Analysis runs on the AI you connect, and our server checks your license and fetches the pages of links you save, as described in the Privacy Policy. There is no mug account. You must be at least 18.

2. Your license

• A mug license costs US$19 as a one-time payment, plus any taxes shown at checkout. There is no subscription.
• It’s for one person, on up to 3 Macs you use. You activate it with a license key and can move it by deactivating a Mac.
• It includes 12 months of updates from the day you buy it. After that, the version you have keeps working, and new updates need a renewal.
• Creem sells the license as our merchant of record, so it handles payment, tax and your receipt, under its own terms. The license itself comes from us.

3. Refunds

You can get a full refund if you ask within 7 days of buying, by writing to diego@getmug.dev, and we give any refund the law requires. A refunded license stops being active, and section 5 applies.

4. Beta licenses

A free beta license lets you use mug for 60 days from the day you claim its key, for one person on up to 3 Macs. We can’t extend a key; we may offer a new one, but we don’t promise to. We may revoke a beta license that was shared, resold or used against these terms. mug in beta may change or have bugs, so keep your own backups: mug can make them in Settings.

5. When a license ends

If a beta license ends, or a license is refunded or revoked, mug stays on your Mac and your library stays yours. You can still open, search and back it up, and coding agents you connected can still read your approved patterns. Capturing, AI processing, approving and editing patterns, and page fetching stop until you enter a new key. Page fetching also needs mug to reach our server.

6. The AI you connect

• Your use of the AI you connect is between you and its provider, under its terms and at your cost. A license covers mug, not your provider’s charges.
• Using a Claude or ChatGPT plan. With your agreement, mug can use Claude Code or Codex, programs you installed and signed in to yourself, so that analysis uses your plan’s limits. mug doesn’t read or keep your credentials. Anthropic hasn’t approved this for third-party apps and OpenAI hasn’t confirmed it, so it could stop working or affect your account with them. You choose whether to use it, you’re responsible for following their terms, and you can use an API key instead. We don’t promise this option will stay available.

7. Your content

You own what you submit and the patterns made from it. You give us permission to fetch and process it only to run the Service for you. We don’t sell your content or use it to train AI. You confirm you have the right to submit it, including to the AI you connect.

8. AI output may be wrong

Patterns, titles and comparisons are generated by AI and may be wrong, incomplete or out of date. You review and approve patterns before mug offers them to your agents, and you are responsible for the code your agents produce.

9. Connecting coding agents

When you connect an agent, mug installs its plugin through that agent’s own tools. You can disconnect it in Settings. Codex, Claude Code and their model providers are third-party services under their own terms.

10. Acceptable use

Don’t use mug to submit illegal or infringing content, scrape websites at scale or bypass their access controls, or attack or overload our systems or anyone else’s. Don’t sell, share or publish a license key, get around license limits, or copy, modify or resell the app, except where the law allows it. We may revoke a license that does, after telling you when reasonable.

11. Availability and changes

We work to keep mug running but can’t promise it will be uninterrupted or able to fetch every site. We may change features; if a change materially reduces what you paid for within your 12 months of updates, we’ll tell you first. If we shut the server down, we’ll give 30 days’ notice. The app and your library stay on your Mac, and we’ll aim to leave your license working without the server.

12. Our software

The app, service and brand belong to us. You may use the app on Macs you control while you follow these terms. Open-source parts keep their own licenses.

13. Disclaimer and liability

The Service is provided “as is”. To the extent the law allows, we aren’t liable for indirect or consequential losses, and our total liability is limited to the amount you paid us in the 12 months before the claim. These limits don’t apply where the law forbids them, and nothing here removes consumer rights you can’t waive.

14. Changes to these terms

We’ll tell you about material changes in the app or by email 30 days before they take effect.

15. Law and disputes

These terms are governed by the laws of Brazil. Disputes go to the courts of São Paulo, SP, Brazil, without prejudice to the mandatory consumer-protection rules of your country of residence.
