Terms of Service
Updated August 31, 2026
These terms are between you and Rafacst, the publisher of Deck³. By installing, accessing, or using the app, you confirm that you have read and agree to these terms and to the Privacy Policy. If you use the app on behalf of a company, you represent that you have authority to bind it.
1. Minimum age
Deck³ is not directed at children or adolescents, and the Privacy Policy states that Rafacst does not knowingly process their personal data. Accordingly, you must be at least 18 years old to use the app. Where the age rating the app carries in its store permits a younger user, a person aged 16 or 17 may use it only with the consent and supervision of a parent or legal guardian, who accepts these terms on their behalf and is responsible for that use. The store's age rating applies in addition to this clause, and the stricter of the two governs. If Rafacst learns of use in breach of this clause, it may terminate access under section 13, and personal data will be deleted as described in the Privacy Policy.
2. What Deck³ is
Deck³ is a third-party client for Bluesky and the AT Protocol, for macOS and Windows. It is not official, and it is neither affiliated with nor endorsed by Bluesky. Rafacst does not operate the network, does not host its content, and does not control its moderation.
3. Licence to use
Rafacst grants you a personal, limited, non-exclusive, non-transferable licence to download, install, and use Deck³ on devices you control, under these terms and the applicable store rules. Updates and supplements are covered unless they come with separate terms. For a copy obtained through the Microsoft Store, this licence provides at least the download, installation, and usage rights required by the applicable Microsoft Usage Rules. The licence does not transfer ownership of the software.
4. Your Bluesky account
Deck³ uses the Bluesky account you already hold: network features require that account, while demo mode works without signing in. You are responsible for keeping your credentials secure and for activity carried out under your account. A handle or email address and an app password are sent directly to the PDS you select; Rafacst does not receive them, and the app password is not retained after sign-in. You must also comply with the terms applicable to your Bluesky account and to your PDS.
5. Price
Deck³ is currently offered free, with no in-app purchase and no subscription. Rafacst does not receive card details. If a paid feature is introduced, its price and conditions will be shown before any confirmation, and charges, cancellations, and refunds will be processed by the store you bought through, under that store's rules. Nothing in these terms limits a mandatory cancellation, cooling-off, warranty, or refund right under applicable consumer law.
6. Acceptable use
You agree to use the app lawfully and consistently with its purpose. You must not: attempt to access systems or data improperly; interfere with the app's operation; reverse engineer beyond what the law permits; violate third-party rights; or use the app for illegal, fraudulent, deceptive, harassing, exploitative, or abusive purposes. You must also comply with the rules of the Bluesky service and of the PDS through which you reach the AT Protocol.
7. Your content
You retain ownership of content you create. Rafacst claims no licence to content sent through Deck³ and does not host it; at your direction, the app transmits it to your PDS and to the AT Protocol services you use. Their terms determine any licence you grant them, their moderation, and their retention or deletion practices. Because the AT Protocol is decentralized, deleting content from your account may not remove copies already held by independent services.
Deck³ displays content created by other users of Bluesky. You may not use the app to create, share, promote, or facilitate content or conduct that is illegal; exploits or endangers children; contains non-consensual intimate material; threatens violence; harasses or discriminates; impersonates or deceives; infringes privacy, intellectual-property, or other rights; distributes malware or spam; or evades applicable moderation, labeling, age-assurance, or safety controls. Bluesky's Community Guidelines and the rules of your PDS also apply.
8. Reporting and moderation
In the app, Report Post and Report Account submit reports to Bluesky's moderation service. You can also mute or block accounts, mute threads and words, and use the content filters and labelers associated with your account.
To report content that appears in Deck³ to Rafacst, email [email protected] with a link or other identifier for the content and enough detail for review. Never send a password or a session token. Rafacst reviews reports that identify content displayed in the app and may take the steps reasonably available to it, including limiting the content's display or access in the app where technically practicable, notifying the relevant hosting or moderation service, and complying with lawful or store requests to disable content.
9. Intellectual property
The app, its name, trademarks, layout, text, images, and code are owned by Rafacst or its licensors and are protected by law. These terms grant you no rights over those trademarks or the software beyond the licence in section 3.
10. Third-party services
Deck³ integrates with third-party services: Apple, Microsoft, Bluesky and other AT Protocol services, KLIPY (GIF search and delivery in the composer), translation and link-preview services, and the analytics instance described in the Privacy Policy. These services have their own terms and may fail, change, suspend an account, remove content, or return incomplete data. Rafacst does not control them, and using the app does not alter the agreement between you and the relevant provider. The full list, with what each receives and where it processes it, is in the Privacy Policy.
Content served by a third party. Where a feature displays media supplied by a third-party catalogue, such as the GIF picker, that media is that provider's content, served from its systems and subject to its own terms and moderation. Rafacst does not host it and does not review it in advance.
Apple. For a copy obtained from the App Store, the following applies. This agreement is between you and Rafacst only, not with Apple, and Rafacst alone is responsible for the app and its content. Apple has no obligation whatsoever to furnish any maintenance or support services in respect of the app. If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the app to you; to the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the app. Rafacst, not Apple, is responsible for addressing any claim that the app or your possession or use of it infringes a third party's intellectual property rights, and for any product liability claim, any claim that the app fails to conform to a legal or regulatory requirement, and any claim under consumer protection or similar legislation, subject to the limits in these terms and to any mandatory right you hold under Brazilian law. You represent that you are not located in a country subject to a United States Government embargo or designated as a "terrorist supporting" country, and that you are not listed on any United States Government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these terms and, upon your acceptance, have the right (and are deemed to have accepted the right) to enforce these terms against you as a third-party beneficiary. Nothing in this paragraph limits the mandatory consumer rights described in sections 12 and 14.
11. Availability and changes to the app
Rafacst may change, improve, suspend, or remove features to fix problems, add capabilities, adapt to technical change, comply with legal requirements, or adjust third-party integrations. Reasonable efforts are made to keep the app available, but uninterrupted or error-free operation is not guaranteed. Feature availability may vary by device, system, region, permissions, settings, and third-party service availability. This notice does not limit any statutory consumer right.
12. Warranties and liability
The app is provided "as is" and "as available", without warranties of any kind beyond those required by law. Rafacst does not warrant that the app will meet all your specific needs or be free of faults. This does not exclude the legal warranties applicable to consumers.
To the maximum extent permitted by applicable law, Rafacst is not liable for indirect or incidental damages or lost profits arising from the use of, or inability to use, the app. Nothing here excludes or limits liability where doing so is prohibited by law, including mandatory consumer warranties and liability arising from fraud, intentional misconduct, gross negligence, or personal injury. In Brazil, the protections of the Consumer Protection Code remain fully applicable.
13. Termination
You may stop using the app at any time by signing out or uninstalling it. Signing out or uninstalling removes or affects local app data as described in the Privacy Policy, but does not delete your Bluesky account, posts, messages, or other remotely stored content: manage those through your PDS or your Bluesky account controls. Rafacst may suspend or terminate access in case of a breach of these terms or use that endangers the service or third parties, but it does not control whether Bluesky or another PDS suspends its own account. On termination, clauses that by their nature should survive remain in force.
14. Governing law and venue
These terms are governed by the laws of the Federative Republic of Brazil, in particular the Consumer Protection Code (Law No. 8.078/1990) and the Internet Civil Framework (Law No. 12.965/2014). The courts of the consumer user's domicile are elected to resolve any dispute.
15. Changes to these terms
These terms may be updated prospectively to reflect changes in the app, in legal requirements, or in operational practice. The current version and its date are published on this page. Where required, reasonable notice of a material change is given. Changes do not reduce rights already accrued or mandatory rights under applicable law. If you do not agree to revised terms, you may stop using the app.
