FISH ON THE SIDE · PRIVACY
Your aquarium stays with you.
Privacy information for this offline development build.
Updated November 5, 2026
What stays in your browser
FLOW鱼DEN saves your fish, names you give them, collection, care records, game resources, puzzle progress and preferences in this extension’s local browser profile. The latest 48 factual aquarium memories, including any name recorded at the time, stay there after a fish leaves. Recovery snapshots stay in that profile too.
This build has no cloud sync, account service, analytics, advertising or active payment integration. FLOW鱼DEN does not send your aquarium, browsing activity or usage history to a developer server.
Files you choose to save
Save & help lets you download a backup and choose a file to import. Both operations run on your device. A backup may contain your fish names and other aquarium progress, so share it only when you intend to share that information.
Game backups carry progress, not proof of purchase. Importing one does not create a purchase or restore a paid licence.
Postcards you choose to share
Aquarium, fish and memory postcards are generated on your device from local game artwork. A memory card includes its event and date, illustrated with your current landscape; it is not a screenshot of the aquarium at that earlier time. Saving a PNG does not upload it or post it to a social network. Cards contain the FLOW鱼DEN brand and public product website; they leave out balances, save identifiers and fish names unless you explicitly choose to include a fish name. You decide where to send the saved image or copied website link.
Browser access
FLOW鱼DEN uses local storage and the browser’s side panel. It does not request permission to read your web pages, browsing history, browser account or payment details.
Optional reminders
Reminders are off by default. Only clicking the enable button requests the browser’s optional alarms and notifications permissions. If you agree, the extension checks local aquarium readiness and can show a quiet browser notification for new arrivals or a returned expedition. There are no hunger warnings or missed-day penalties. Preferences and reminder bookkeeping stay in your browser; no notification server, push subscription, account or tracking service is used.
Reminders are limited to once per time away and at least six hours apart. They require your browser to be running and may be delayed during sleep or after it closes. You can turn them off in reminder settings or revoke their permissions in your browser. Reminder checks do not update your game save or claim rewards.
Control and recovery
You can save a backup, inspect an import before replacing your aquarium, or restore a recent local snapshot from Save & help. Replacement keeps a recovery point. Uninstalling the extension or deleting browser-profile data can remove local progress and snapshots, so keep a downloaded backup when you need a separate copy.
Help and diagnostics
Open Save & help in the aquarium for troubleshooting. Copying diagnostics is optional and does not send a message. The diagnostic text leaves out fish names and the full save. If you share a downloaded aquarium backup separately, it contains more information.
Support and security contact:
External links open only when you choose them. Copying support details does not send a message.
Future online features
Purchases and purchase recovery are unavailable in this build. Any future online service will need an updated disclosure before it begins handling your information.
