Privacy Policy

Local processing

Documents you open or create, recent-document references, annotations, and preferences are normally processed and stored on your device. MarkDeck does not receive this local content unless you choose a feature that sends it elsewhere. Your device may include app data in a system backup according to its settings. You control local copies by deleting content, clearing app data, uninstalling, or managing those backups.

Optional online features

• Connected storage and sync: when you connect an account and select content, MarkDeck sends that document data, synchronization metadata, and the account identifiers needed to operate the connection. Disconnecting stops future access by MarkDeck but does not delete copies in a space you control.
• URLs and remote resources: opening a URL, remote image, asset, or font sends the requested address and ordinary network information to the destination serving it.
• Feedback and contact: MarkDeck receives the message, category, app context, technical details, and optional email you submit. Email is optional unless you want a reply. Do not include personal information that is not needed for your request.
• Notifications: with permission, MarkDeck uses a random installation ID, notification token, language, platform, time zone, app version, and activity timestamps to deliver and measure notifications. Denial or revocation prevents future registration and triggers deletion of the current registration when possible.
• Purchases: purchase and restoration use store, product, entitlement, transaction, and app-instance information. MarkDeck does not receive your payment-card details.

Diagnostics, measurement, and advertising

Firebase Crashlytics automatically processes crash and operational diagnostic data in distributed production builds to keep MarkDeck reliable. This may include a technical installation identifier assigned by Firebase, app and operating-system versions, device characteristics, stack traces, timing data, and MarkDeck's closed operational fields. MarkDeck's own diagnostic fields do not include document content, names, paths, URLs, selected text, or document-derived identifiers. Crashlytics diagnostic records are kept for up to 90 days. Crashlytics operates independently from Analytics: enabling crash diagnostics does not enable Analytics. Usage measurement remains disabled until the applicable separate in-app choice enables it. Advertising and related identifiers depend on your tier, region, consent choices, and system permissions; Pro removes MarkDeck's in-app ads.

Recipients and transfers

Information is sent only to categories of services needed for your chosen feature or to operate MarkDeck: connected storage, app infrastructure, diagnostics and measurement, advertising, purchase processing, notification delivery, website security, and customer support. These services may process information in other countries under applicable safeguards. MarkDeck does not sell messages or document content.

Retention and deletion

• Local data remains until you delete it, clear app data, uninstall, or manage a system backup. Connected-storage copies remain under your control after disconnection.
• In-app feedback is kept for no more than 365 days; feedback operational logs for 30 days.
• Notification registrations are deleted after permission is revoked when reachable, with a 270-day inactivity fallback. Delivery ledgers are kept for 90 days.
• Installation-level notification evidence is removed when a daily result becomes final; only aggregate counts remain.
• Website access logs are kept for 90 days and superseded website versions for 30 days.
• Firebase Crashlytics diagnostic records are kept for up to 90 days.
• Other diagnostic, measurement, advertising, and purchase records follow the applicable category's criteria and controls below.

Your choices

You can use local document functions without connecting storage, submitting feedback, or granting notifications. You can change consent and advertising choices in the app or system settings, revoke notification permission, disconnect storage, manage purchases through the app store, delete local content, and contact MarkDeck about data it controls. Some online features cannot work without the data needed for that feature.

Rights, security, and limits

Depending on where you live, you may have rights to access, correct, delete, restrict, object to, or obtain information about personal data. Email [email protected] with the minimum information needed to locate your request. MarkDeck will respond as required by applicable law. Reasonable safeguards are used, but no networked system can be guaranteed completely secure.

Children

MarkDeck is not directed to children who cannot validly consent to the applicable online features. If you believe a child submitted personal information, contact MarkDeck so it can be reviewed and, where appropriate, deleted.

Google Workspace API data

MarkDeck's use and transfer to any other app of information received from Google Workspace APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements.

Changes

This policy may change when MarkDeck's behavior or legal obligations change. The effective date will be updated, and material changes will be communicated through an appropriate surface when required.
