Signing in
HydroGardenAdvisor uses passwordless sign-in: enter your email address and we send a one-time 8-character code, valid for 15 minutes. Enter the code and you’re signed in — there’s no password to create or remember.
If a code doesn’t arrive, check your spam folder first. Codes expire after 15 minutes, and you can request a fresh one at any time.
Restoring a purchase
If you’ve subscribed to Pro and it’s not showing up — for example, after reinstalling the app or switching devices — open Settings in the app and tap Restore purchases. This re-checks your purchase history with the App Store or Google Play and re-applies your subscription without charging you again.
Pro attaches to your account, not just your device: sign in with your email first, then tap Restore purchases again.
Deleting your account
You can delete your HydroGardenAdvisor account and all associated data at any time, directly in the app: open Settings, under Account choose Delete account, and confirm. Deletion is immediate.
You can also request deletion by email — see the Account and data deletion section of our Privacy Policy for the exact steps and what gets deleted.
