Cohabit: Tank Tenants is your pocket compatibility composer — check dwellers against each other by temperament, size and layer before they ever share water or substrate.
No guesswork, no forum-scrolling at 1am — just clear answers before you commit a new tenant to your tank.
Cross-check any two species for temperament clashes, size mismatches, and territorial conflict before they meet.
Visualize who claims the top water, mid water, substrate, or land zone so nobody's crowding a neighbor's turf.
Flags for peaceful, semi-aggressive, and territorial dwellers, so boisterous tenants don't bully the shy ones.
Plans around full-grown size, not the cute juvenile in the shop tank, to avoid outgrown enclosures and surprise predation.
Works across aquariums, terrariums, vivariums, and paludariums, matching setups to each species' real needs.
Every check runs right on your device. No accounts, no cloud sync, no data leaving your pocket.
Pick two dwellers and see how our engine reasons about temperament, layer, and size before giving a verdict.
We collect nothing. Cohabit: Tank Tenants does not ask for your name, email, location, photos, or any personal identifiers. There is no account to create and nothing to submit to us.
Because no information is collected, none is used, analyzed, profiled, or sold. Your compatibility checks, species lists, and tank plans belong entirely to you and are never reviewed by us.
All species data, saved tank setups, and compatibility results are stored locally on your device only. Nothing is uploaded to a cloud server, and we operate no backend database that could hold your information.
The app contains no third-party analytics software, advertising networks, or tracking pixels. We do not share data with outside companies because no data is ever gathered in the first place.
Since your information never leaves your device, there is no transmission to intercept and no remote database to breach. Your tank plans are as secure as the device they live on.
Cohabit: Tank Tenants is safe for users of all ages, including children. We do not knowingly or unknowingly collect personal information from anyone, regardless of age, in full alignment with COPPA principles.
There are no accounts to manage and no servers holding your data, so there is nothing for us to delete on request. Uninstalling the app permanently removes all locally stored data from your device.
If our practices ever change, we will update this policy and revise the Effective Date above. We encourage checking back occasionally, though our core promise of local-only, no-collection design will not change.
Questions about this policy can be sent to privacy@cohabittanktenantsapp.com.
