Koi Companion Support

Need help with Koi Companion?

Koi Companion is operated by West Coast Aerial Ltd, registered in Scotland under company number SC743590.

Getting the app

On a phone or tablet, install Koi Companion for Android from Google Play. On a desktop or laptop, use it in your browser at app.koicompanion.app. Neither needs an invitation.

The iPhone and iPad release is being finalised. Email us if you would like to be told when it is available, and never post your account email in a public comment.

Koi Companion is currently free to use. After full launch, a subscription fee will be required to help cover ongoing operating and development costs. Subscription options and prices are shown in the app's Subscription section.

Delete your Koi Companion account and data

You can request deletion even if Koi Companion is no longer installed.

In the app, sign in and go to Settings → Your account → Delete my account, then confirm the request.
If you cannot access the app, email koicompanion@gmail.com from the address used for your account with the subject Account deletion request.
We may reply to verify that the request came from the account holder. Never send a password, one-time code or payment details.

Requests are reviewed and processed manually, so submitting a request does not immediately remove data.

What is deleted

After a verified request is completed, we delete the Koi Companion sign-in account and data linked to it from our active systems. This includes profile and account identifiers; pond, tank, koi, water, care, health, treatment, diary, reminder and report records; uploaded photos, videos, evidence and documents; Koi Companion AI prompts, results and saved context; messages, support attachments and device notification tokens.

What may be kept

Limited records may be retained only where reasonably required for security, fraud prevention, legal obligations, financial or subscription reconciliation, disputes, or routine backup expiry. App-store purchase records held by Google or Apple are controlled by those providers. Content that you deliberately shared with another user or exported may remain in copies outside your account.

We aim to complete a verified deletion request within 30 days. If a legal requirement or unresolved dispute requires longer retention, we will explain this when we respond. Export anything you need before requesting deletion.

Other privacy requests

For access, correction or other privacy requests, email koicompanion@gmail.com with the subject Privacy request.

Fish health note
