LastBuy SG ("the app", "we", "our") is a personal grocery price tracking app. This policy explains what information the app collects, how it's used, and how you can control it.
LastBuy SG collects only what's needed to run your account and store your data:
We do not collect location data, contacts, or any device data beyond what's needed for the app to function.
Your data is stored on Supabase, a secure cloud database provider, over an encrypted connection (HTTPS/TLS). Row-level security policies prevent other users of the app from reading or writing your entries. The app's operator can access stored data through Supabase's administrative tools to run and maintain the service, investigate problems, and prevent abuse.
Your data is used solely to provide the app's core functionality: letting you log, view, and track grocery prices over time. We do not sell your data, and we do not use it for advertising.
We do not share your personal data with third parties, except with the service providers that power the app (Google, for sign-in, and Supabase, for secure storage), each of which processes data only as needed to provide their service to us. If a future version of LastBuy SG introduces optional data sharing (for example, a shared price list between two users), that feature will be opt-in and this policy will be updated to describe it before it launches.
Your data is retained for as long as your account is active. You can request deletion of your account and all associated data at any time from the app's Menu ("Delete account"), or directly at /delete-account.html, by emailing billylabswork@gmail.com. Deletion requests are processed promptly.
LastBuy SG is not directed at children under 13, and we do not knowingly collect data from children under 13.
We may update this privacy policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
Questions about this policy or your data can be sent to billylabswork@gmail.com.
