Version 0.15, October 31, 2026.

These terms are an agreement between you and StackBlender LLC, a Michigan limited liability company (“StackBlender”, “we”, “us”), the maker and seller of Apollo Super. These terms govern using Apollo Super and our online services; Pro is bought through Google Play, under Google Play’s terms, and buying it is also governed by our terms of sale and refund policy. By selecting Accept when Apollo Super presents these terms to you, you agree to them. If you don’t agree, don’t use Apollo Super. If you aren’t legally able to agree to these terms on your own, you may use Apollo Super only with the permission of a parent or legal guardian who can agree to them for you. Questions: support@stackblender.com.

In short: Apollo Super is free. Pro is a one-time purchase through Google Play, on your Google account; it unlocks Pro’s features and hosting online play. Friends join free, and there’s no account to create. Online play is provided as available: connections are made directly when possible, and on some networks online play may be unavailable at times. Nearby play on the same Wi-Fi is free. You get a license to use the app; we don’t claim ownership of your game files, saves, screenshots, recordings, shells, styles or other user content. This summary is for convenience: the sections below are the terms, and they control if there’s any difference.

1. Definitions

  • Apollo Super: the Android app made and distributed by StackBlender, with its updates.
  • Pro: the one-time paid purchase that unlocks Apollo Super’s Pro features.
  • Online play: playing with someone over the internet, in a room or by invite link, as section 6 describes.
  • Online services: StackBlender’s servers that Apollo Super uses: online rooms, our connection service (the relay), the check of Pro for hosting, and problem reports.

2. Your license to use Apollo Super

We give you a personal, limited, non-exclusive, non-transferable license to install and use Apollo Super, and the Pro features you’ve bought, on devices you own or control, subject to these terms and subject to termination only as provided in these terms. Your use may include ordinary play and making recordings, streams, reviews and other lawful content showing Apollo Super, monetized or not, but not reselling, sublicensing or commercially hosting Apollo Super, or offering Apollo Super itself as a commercial service.

Except as allowed by applicable law, by Google Play’s own functions, or by an open-source license (section 3), you may not copy, sell, rent, lend, sublicense, redistribute, modify, reverse engineer, decompile or disassemble Apollo Super; get around, disable or tamper with its purchase checks, Pro features or online service limits; or use it to break the law or anyone’s rights. These restrictions don’t limit rights that applicable law or an open-source license gives you and that these terms can’t lawfully restrict.

Apollo Super, its code, art, sounds and text, and the Apollo Super and StackBlender names and logos belong to StackBlender LLC or its licensors. Except for rights separately granted under applicable open-source licenses, this license doesn’t give you any ownership rights in them. All rights not expressly granted are reserved.

3. Open-source and third-party software

Apollo Super includes open-source and third-party software, including ares under the ISC License, libdatachannel and libjuice under the Mozilla Public License 2.0 (“MPL 2.0”), components under the zlib License, and components under other licenses, all listed in Settings > Help & feedback > Licenses & notices. Each component is governed by its own license. Nothing in these terms limits the rights those licenses give you, and if these terms conflict with a component’s open-source license about that component, the open-source license controls.

The MPL 2.0 components are used unmodified; their source code is at the addresses Licenses & notices gives. Apollo Super’s sound processor start-up program, its DSP-1, DSP-2 and ST010 chips and its Cx4 chip’s data tables are StackBlender’s own work, also published under the GNU General Public License, version 3 or later, at the addresses Licenses & notices gives.

4. Your games and your content

Apollo Super doesn’t include games, ROMs, the console maker’s firmware or other copyrighted game content. You’re responsible for having every right and permission needed to use any file you open with Apollo Super, including any copy or backup you make. Laws on copying games, backups, archival copies and technical protection measures differ between countries. Apollo Super’s multiplayer doesn’t transfer game ROM files between players: each player needs their own copy. It transmits only the game and synchronization data needed to establish and maintain play together: because both devices run the host’s game, that includes the host’s game state, with its save, when they connect.

As between you and StackBlender, we claim no ownership of your saves, save states, cheat codes, screenshots, recordings, shells or styles. You keep whatever rights you have in them. This doesn’t give you rights in the games, artwork, music, characters, trademarks or other material they contain or show, which belong to their owners.

When you choose to send a problem report, you grant StackBlender, and service providers acting on our behalf, a non-exclusive, worldwide, royalty-free license to access, copy, analyze and use the report and what’s in it, only as reasonably needed to investigate it, give support, improve or secure Apollo Super, and prevent similar problems. Our Privacy Policy says what a report contains and how long it’s kept.

5. Pro

Pro is a one-time purchase, not a subscription: there’s no recurring charge. Subject to these terms and applicable law, it unlocks the Pro features of that purchase for the Google account that bought it through Google Play, on supported versions of Apollo Super. Pro starts immediately after purchase. Where the law gives you a 14-day right of withdrawal (for example in the EU or UK), you lose it once Pro starts if you agreed to Pro starting at once and acknowledged losing that right; on Google Play, you give that agreement under Google Play’s terms. “Pay once, yours forever” means Pro’s features in the app: they don’t expire. Pro also includes hosting online play (section 6), which depends on our online services. Losing Pro never locks your saves, save states or resume points.

Free trial. You can try Pro’s features in the app free for 5 days, once on a device. A trial doesn’t include hosting online play; it ends on its own, bills nothing and needs no payment details.

If you live in Quebec: the next paragraph applies to you only to the extent the Consumer Protection Act (Quebec) allows it.

We may change, replace or discontinue individual Pro features where reasonably necessary for security, legal compliance, compatibility, technical changes, changes to third-party services, or Apollo Super’s continued operation. We won’t intentionally remove substantially all of the functionality of a Pro purchase to require you to buy it again, or move the same functionality to another paid tier. This doesn’t limit changes reasonably necessary for the reasons above, or any rights or remedies applicable law gives you. If you live in Quebec, a change to a Pro feature reaches you as section 14 describes for Quebec, with the same right to refuse it.

6. Online play

  • Hosting and joining. Hosting online play comes with Pro, bought for Apollo Super from the store you installed it from; there’s no account to create or sign in to. Joining is free and needs neither Pro nor a sign-in. Nearby play (devices on the same Wi-Fi) is free and doesn’t use our online services.
  • Rooms and invite links. You can play online in a room (a code your friend enters) or by an invite link you send your friend, who sends a reply link back. In some countries online play is by invite link only, connecting the devices directly, without our rooms or connection service.
  • As available. Online play is provided as available. Apollo Super connects the devices directly when their networks allow it. Some networks need our connection service, which has capacity limits and may be unavailable: it may be busy at times, a relayed game may give up its connection while nobody is playing, and a long relayed game may ask whether you’re still playing. Reasonable technical, security and anti-abuse limits apply to the services that set games up.
  • Current version. Online play needs a current version of Apollo Super. When an update is needed, Apollo Super says so before you host or join; offline and nearby play aren’t affected.
  • If Pro is refunded. If your Pro purchase is refunded or revoked, hosting stops.
  • If our online services change or end. Our online services, including how online play connects (for example, our room and connection services, or direct invite links), may change or end. We’ll give at least 90 days’ notice in the app and on our website. When our services end, an update keeps online play available through direct invite links where networks allow, and everything else in Pro keeps working. We may act sooner only where the law, a security threat or a failure of third-party infrastructure requires it, limited to what’s reasonably necessary, with any remedy applicable law requires. If you live in Quebec, a change to online play also reaches you as section 14 describes for Quebec, with the same right to refuse it.
  • Interruptions. Online services may sometimes be unavailable because of maintenance, outages, security incidents, failures of third-party infrastructure, network conditions, or events outside our reasonable control. This doesn’t affect any refund, price reduction or other remedy applicable law gives you.

7. Using our online services

Don’t: try to gain unauthorized access to the online services or to another player’s device or data; introduce malware; interfere with, probe, scan, overload or disrupt the services; get around usage limits; use automated means in a way that materially burdens the services; resell, share or transfer Pro; use our connection services to send anything other than Apollo Super’s own play; or harass other players.

We may restrict, suspend or end access to online services when we reasonably believe these rules have been materially broken. We may act immediately where reasonably necessary for security, fraud prevention, abuse prevention, legal compliance, or the protection of players or the services; for other breaches, where appropriate and practicable, we’ll give notice and a chance to put things right.

Optional integrations such as Google Drive and RetroAchievements are provided by third parties and are also subject to their terms and privacy practices. Their availability and features aren’t under StackBlender’s sole control.

8. Updates

We may update Apollo Super to fix problems, add features, or keep it working with Google Play and Android. Some features, particularly online ones, may need a current or minimum supported version. Where applicable law requires us to provide updates to keep paid digital content or services in conformity, nothing in this section limits that.

9. Warranties

If you live in Quebec: this section doesn’t apply to you to the extent the Consumer Protection Act (Quebec) doesn’t allow it.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, APOLLO SUPER AND THE ONLINE SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE”, AND STACKBLENDER DISCLAIMS IMPLIED WARRANTIES, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT, EXCEPT WHERE THEY CAN’T LAWFULLY BE DISCLAIMED. In plain terms: we work to keep Apollo Super and its services running and correct, but we don’t promise they’ll always be available, work with every game or device, or be free of errors. Keep your own backups of your saves.

10. Liability

If you live in Quebec: this section doesn’t apply to you to the extent the Consumer Protection Act (Quebec) doesn’t allow it.

To the maximum extent permitted by applicable law:

  • StackBlender isn’t liable for indirect, incidental, special, exemplary, punitive or consequential damages, including loss of use, loss of opportunity, or loss of data to the extent it’s legally a consequential damage; and
  • StackBlender’s total aggregate liability arising out of or relating to Apollo Super, the online services or these terms won’t exceed the greater of (a) what you paid for Apollo Super products and services in the 12 months before the event giving rise to the claim, or (b) US$50.

Nothing in these terms excludes or limits liability that can’t lawfully be excluded or limited, including, where applicable law doesn’t allow it to be limited, liability for fraud or fraudulent misrepresentation, willful misconduct, gross negligence, death, bodily or moral injury, or breach of mandatory consumer rights.

11. Your rights as a consumer

Nothing in these terms excludes, restricts or modifies any warranty, guarantee, remedy or other consumer right that applicable law doesn’t allow us to exclude, restrict or modify: for example, your rights under the Australian Consumer Law, under New Zealand’s Consumer Guarantees Act and Fair Trading Act and, in the EU and the UK, your statutory rights for digital content and digital services.

If you live outside the United States, you keep the protection of the consumer and data-protection laws of your country or province that can’t be contracted out of. Where those laws give you a right to cancel a purchase, to a refund, to a repair or replacement, or to bring a claim in your own courts or before a consumer body, nothing in these terms takes it away. Google Play’s refund rules apply to purchases made there in addition to, not instead of, those rights.

12. Ending this agreement

You can end it at any time by uninstalling Apollo Super.

If you live in Quebec: the next paragraph applies to you only to the extent the Consumer Protection Act (Quebec) allows it.

We may suspend or end your access to online services for a material or repeated breach of section 7. We may end your license to Apollo Super if you materially breach the restrictions in section 2, or where the law requires it. Where a breach can reasonably be put right and doesn’t present an immediate security, legal or abuse risk, we may give you a reasonable chance to put it right first.

Provisions that by their nature should continue after this agreement ends will continue, including those on ownership and reserved rights, open-source licensing, your content, warranties, limitation of liability, consumer rights, disputes, and rights and obligations already accrued.

13. Google

Google isn’t a party to these terms between you and StackBlender and isn’t responsible for developing, maintaining or supporting Apollo Super. Google Play, and any purchase made through it, remain subject to Google’s applicable terms and policies.

14. Changes, disputes, law and the rest

We may update these terms from time to time. We’ll update the effective date and give reasonable notice of material changes. Changes apply from their stated effective date and don’t change rights or obligations that arose before it. If a material change affects something you’ve paid for, we’ll give any further notice, way to consent, right to cancel, refund or other remedy applicable law requires, and where appropriate we may ask you to accept the revised terms before you continue to use the affected services. If you live in Quebec, we’ll send you the notice in writing at least 30 days before the change takes effect, giving that date, the old and new text, and your right to refuse the change; you may refuse it and cancel the affected service, without cost, penalty or cancellation indemnity, by telling us within 30 days after the change takes effect.

If you have a problem with Apollo Super, please write to us first at support@stackblender.com so we can try to put it right. Nothing in these terms requires arbitration or stops you from taking part in a class action, and you may always use a small-claims court or a consumer body where the law lets you.

If you live in Quebec: the choice of law and courts in the next paragraph doesn’t apply to you to the extent Quebec law doesn’t allow it, and you may bring a claim in Quebec.

These terms are governed by the laws of the State of Michigan, USA, without regard to conflict-of-law rules. If you’re a consumer living outside the United States, you may also bring a claim in the courts of your country or province where its law gives you that right, and its mandatory consumer law applies to you regardless of the choice of Michigan law. Otherwise, any dispute arising from these terms will be brought in the state courts located in Ingham County, Michigan, or the United States District Court for the Western District of Michigan, if it has subject-matter jurisdiction, and you and StackBlender consent to the personal jurisdiction of those courts.

These terms are provided in English and in French. If you live in Quebec, you are bound by the English version only if the French version was given to you before you accepted these terms and, after it was given to you, that is your express wish; otherwise, the French version is the one that binds you.

Apollo Super keeps on your device which version of these terms you accepted, when, and in which language, and we keep every version of these terms we publish.

If part of these terms can’t be enforced, the rest still applies. These terms are the agreement between you and StackBlender about your license to and use of Apollo Super and the online services, except for additional terms expressly identified as applying to a particular feature. Buying Pro is also governed by our terms of sale and refund policy; Pro bought on Google Play is also subject to Google Play’s terms. Open-source licenses, Google Play’s terms and third-party services’ terms apply separately where relevant. Our Privacy Policy describes how we handle personal information.
