Production-behavior summary · Updated August 1, 2026

Important

This page explains TankWise behavior for customers. It does not replace the Google Play Data safety form or Apple App Privacy answers, which must be completed inside the store portals against the final production build.

Stored on the device

The following information can be stored in private local app storage and is not transmitted to a TankWise aquarium server:

  • Tank names, size, setup, biotope, and settings
  • Water readings and aquarium notes
  • Fish, invertebrate, plant, stocking, and comparison records
  • Tank, progress, note, and receipt images
  • Local preferences and Unlimited Tanks entitlement state

Android cloud and device-transfer backup are disabled in the current release.

Optional connections

Optional

Online species lookup

Entered fish or plant search text is sent over HTTPS to third-party reference sites when you request a lookup. The query can be received with IP address and user agent.

Only with purchases

App-store billing

The applicable store processes payment. TankWise receives product, purchase, entitlement, and verification information, not card details.

None

Aquarium data cloud

The current app has no TankWise login or aquarium cloud sync. Tank profiles, readings, livestock, plants, and images remain on the device.

Only when submitted

Beta and support storage

Launch-interest requests, beta applications, feedback, and support tickets are stored in the website's native hosted database for access updates, tester selection, coordination, and review or response. Beta applications, feedback, and support tickets are also mirrored to a private Simply Submerged Aquatics Google Workspace spreadsheet. Google Workspace sends submission receipts and beta or support owner notifications through a private delivery queue used for retries. The forms do not accept uploads, and submissions are reviewed through protected owner tools.

Permissions in the Android app

Internet
Used for optional species lookup, app-store billing, and links you choose to open.
Camera
Optional and requested for user-initiated tank, note, receipt, or water-test images. Camera hardware is not required.
Not requested
Location, contacts, microphone, SMS, call log, and broad storage access are not declared in the current Android manifest.

Security, deletion, and sale

  • HTTPS is used for optional online requests.
  • Local aquarium data can be removed from the device.
  • Beta applications and feedback can be deleted by request and are subject to purpose-limited, manually managed retention.
  • The beta dashboard is protected and intended for owner-only access.
  • The Google Workspace beta and support spreadsheet is private and intended for authorized owner access.
  • One-time beta submission receipts are transactional and do not enroll an address in unrelated marketing.
  • Simply Submerged Aquatics does not sell personal data.
  • No independent security review is claimed.

See the full privacy policy and deletion instructions for details.
