Privacy Policy

Last updated: 26 May 2025

Stack (the "App") is provided by StackPoker LLC ("we", "our", "us"). This Privacy Policy explains how we collect, use, disclose and secure your information when you use the App, the stackpoker.gg website (collectively, the "Services"), and the choices you have associated with that information.

Summary in plain language: we collect only the data needed to create your account, power social poker features and keep the app reliable. We never sell your information. You can delete your account at any time.

1. What We Collect

Below we map each piece of data against Apple's App Privacy categories.

Category (Apple terminology)	Data points	Source	Linked to you?
Contact Info	Email address, display name	You	Yes
User Content	Posts, hand histories, images you upload, chat messages	You	Yes

We do not request precise location, contact list, or sensitive personal information.

2. How We Use Your Data

Provide core functionality – create your account, sync hands, display the feed and groups.
Community & social features – publish posts you choose to share and deliver push notifications.
Improve and debug – analyse anonymised usage patterns and crash logs to prioritise fixes.
Keep the platform safe – detect spam or abuse and enforce community guidelines.
Communicate with you – reply to support requests and inform you of important changes.

We process data only for the purposes above and in accordance with this policy.

3. Sharing & Disclosure

We don't sell your data. We share it only with:

Recipient	Purpose	Data shared
Google Firebase (USA/EU servers) • Authentication • Cloud Firestore DB • Cloud Storage • Cloud Functions • Analytics • Crashlytics	Backend hosting, real-time database, file storage, usage analytics, crash diagnostics	Data listed in §1 as required for each service
Apple (App Store, iCloud Push)	Crash symbolication, push delivery	Crash logs, device token

All providers act as processors under contractual terms that limit use to our instructions.

If we are required by law (e.g. valid subpoena) we may disclose data, but only after legal review.

4. Your Choices & Rights

Delete Account & Data – in the App: Settings ▸ Delete my account, or email us (see §10). We erase all personal data within 30 days (legal backups within 90 days).
Edit Profile – change display name or email at any time in Settings.
Opt-out of Push – iOS Settings ▸ Notifications ▸ Stack.
Analytics Opt-out – iOS Settings ▸ Privacy & Security ▸ Tracking (we do not track), or enable Limit Ad Tracking; analytics are aggregated and cannot be linked back once collected.
GDPR / UK GDPR / CCPA – residents may request access, correction, portability or restriction by emailing us.

5. Security

Transport encryption – all network traffic uses HTTPS/TLS 1.2+.
Encryption at rest – Firebase automatically encrypts stored data.
Access controls – Cloud Firestore & Storage are protected by strict security rules; only you and approved service accounts can read your private data.
Internal practices – least-privilege staff access, 2-factor authentication, periodic security reviews.

No system is perfect, but we work to protect your information from unauthorised access, alteration or deletion.

6. Children's Privacy

Stack is rated 17+ and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If we learn that we have inadvertently done so, we will delete it immediately.

7. International Transfers

Data is processed on Google Cloud servers that may be located in the United States or the European Union. We rely on Standard Contractual Clauses and other safeguards for transfers outside your jurisdiction as permitted by GDPR and similar laws.

8. Changes to This Policy

We may update this Privacy Policy to reflect new features or legal requirements. We'll notify you by:

Updating the "Last updated" date above, and
In-app notice or email if the changes are material.

Continued use after those changes means you accept the new policy.
