This website

This site is static. It has no accounts or forms and sets no cookies. It does not load browser analytics beacons or third-party tracking scripts. Cloudflare provides built-in request metrics for operating and securing the site. There is no advertising.

The site is served by Cloudflare, which processes standard connection data (such as IP address and user agent) to deliver pages and protect against abuse, under Cloudflare's privacy policy.

Your browser’s language preference can select a translated page. A language you choose on a content page is saved only in this browser, so it overrides the browser default on later visits. It is not sent to an analytics service. You can switch languages using the page links.

Email

If you email support@stackblender.com, we keep the message so we can reply and follow up. Mail is routed through Cloudflare and stored in a Google mailbox. We don't add you to any list, and you can ask us to delete the thread at any time.

Apollo Emulators purchases

At launch, each app's Pro upgrade is bought through Google Play on your Google account. Online play requires no account or sign-in. Hosting checks your Pro purchase when you start a room. Google Play handles your payment details under its own privacy policy; we never receive card details. Each app's privacy policy below explains its purchases, online play, connected features and data retention. See the terms of sale and refund policy.

Marketplaces

Installs, and purchases of our other products, happen on third-party marketplaces (Google Play, Unity Asset Store, JetBrains Marketplace, Visual Studio Marketplace, npm). Each has its own privacy policy and handles payment and account data. StackBlender receives only what those marketplaces provide to publishers, which never includes payment details.

Products

Core work stays on your device. Optional connected features are called out product by product:

  • Athena Asset Tables. Athena Asset Tables runs entirely inside the Unity editor. It collects nothing, sends nothing, and needs no account or network access.
  • Input Porter. Input Porter runs entirely inside the Unity editor. It collects nothing, sends nothing, and needs no account or network access.
  • OpenAPI Guard (deprecated). Analysis is local. OpenAPI Guard does not upload source code, OpenAPI documents, diagnostics, or repository metadata.
  • Flag Marshal (deprecated). Analysis runs on your machine. Flag Marshal has no hosted backend, account, telemetry, or source upload. Flag keys can reveal unreleased features, so replace them with placeholders before posting anything publicly.
  • Apollo Drive. Read Apollo Drive's privacy policy for details about local data and optional services.
  • Apollo Classic. Read Apollo Classic's privacy policy for details about local data and optional services.
  • Apollo Boy. Your games, saves, and settings stay on your device. Data leaves it only when you choose a connected feature: Google Drive backup, RetroAchievements, or online multiplayer. No ads or analytics SDKs, and no account or sign-in. Pro is a Google Play purchase on your Google account; online hosting checks your Pro purchase. Connections are made directly when possible; on some networks online play may be unavailable at times. The full policy explains what each service receives and how long StackBlender keeps it.

Apollo privacy policies

To ask about or delete data we hold, see Apollo data requests.

Your rights

Depending on the features you choose, we may hold email you've sent us or information processed for online play, as described in the Apollo privacy policies. Ask at any time to see or correct or delete data we hold about you; we answer within 30 days unless applicable local law sets a different period, which takes priority. Each app’s privacy policy explains its country-specific procedures. If your country's law gives you more (the EU, the UK, Canada, Singapore, India and others do), those rights apply and the same address is the way to exercise them, and you can also complain to your country's data-protection authority. The person in charge of the protection of personal information isStackBlender LLC's Privacy Officer: support@stackblender.com,StackBlender LLC, 2222 W Grand River Ave, Ste A, Okemos, MI 48864, United States.

Where your data is kept

StackBlender is in the United States; data is processed there and on Cloudflare's network, which runs in data centres around the world. Using a connected feature from another country sends data across borders; it's protected as this policy says wherever it is.

Changes

If this policy changes, the date at the top changes with it. Material changes will be noted on the product pages they affect.
