Privacy Policy — InkSpace

Updated: 3 November 2026 · com.inkspace.app

Your notebooks and PDFs

Free notebooks, drawings and photos are stored on your device. PDF import and export are processed on the device. Notebook text, drawings, imported pages and photos are never sent to advertising or analytics services, or to an external AI service.

Active Pro subscriptions automatically sync existing notebooks and photos to your private Firebase library. Pro includes 1 GB of cloud storage and 1 GB of total transfers per month. Pro Plus includes 10 GB of each and PDF import with annotations. The last 3 notebook versions count towards storage. Existing lifetime Pro purchases include all Plus features. After subscription expiry, automatic sync stops and the local copies remain accessible. Cloud data is retained with your account until you delete it or request account deletion.

Account and purchase information

Firebase Authentication processes your email address, account identifier and authentication information. Google Play handles payment details; InkSpace does not receive your payment-card number. Our server verifies purchase tokens, order identifiers, subscription status and a hashed account binding to provide and restore the correct access and prevent fraud.

Optional advertising

There are no banner ads. Free users can choose rewarded videos for image insertion, photo covers, additional notebooks after the first 3, and PDF export. Pro users have no ads. Before requesting advertising, Google’s consent flow presents choices where required. Available privacy choices can be reopened in Settings.

The Google Mobile Ads SDK may collect and share IP addresses (which can imply approximate location), app and ad interactions, diagnostic information, advertising IDs, app-set IDs and applicable device/account identifiers for advertising, measurement and fraud prevention. See Google Mobile Ads data disclosures and Google’s Privacy Policy.

Optional usage statistics

Google Analytics usage statistics are disabled by default. You can enable or disable them in Settings. This choice is separate from advertising consent. When enabled, Firebase Analytics processes app activity and device/installation identifiers to understand usage and improve the app. Notebook content is excluded.

Security and retention

Cloud connections use HTTPS/TLS. Access rules restrict private cloud content to its owner, and purchase verification runs on the server. Local files remain on your device; keep backups of important content. Account data is retained while needed to provide the service. Limited purchase and fraud-prevention records may be retained where necessary after deletion, as explained on the deletion page. We do not sell your notebook content.

Your choices and contact

You may request access, correction or deletion of personal data and change your consent choices. To request account deletion, visit the account deletion page. Signing out does not delete local notebooks. Cancelling a subscription is handled separately in Google Play.
