Your data

Delete my data

This page explains how to delete the information associated with our applications, as required by the Google Play user data policy.

Last updated: 3 October 2026

The important part: almost all of our applications require no account and store information on your own device, so you control the deletion: there is no account on our servers to close. The exceptions are Bumko and Mallnest Business, which use an account and store data on our servers: for those apps, see the Apps with an account section below.

Option 1 — Delete from within the app

This is the most precise way, because it lets you remove only what you want to remove:

Open the app and go to the relevant list (for example, the history or the list of records).
Use the delete icon on each item to remove it individually.
If you want to start over, delete every item in the list or use the reset option where the app offers one.

Option 2 — Clear the data from Android

This removes everything the application has stored on the device in one go, without uninstalling it:

Open Settings on your phone.
Go to Apps and choose the app.
Tap Storage.
Tap Clear data (or Clear storage) and confirm.

The exact name of each option may vary depending on the manufacturer and the Android version.

Option 3 — Uninstall the application

When you uninstall, Android removes the app's private storage along with it. Bear in mind that this action cannot be undone: if you want to keep your information, export it from the app first.

System backups

If you have Google backup enabled, the operating system may have backed up the app's data to your Google account. That backup is managed by Google, not ImagoStack, and you can manage it from Settings → Google → Backup.

Requesting deletion in writing

If you would still rather we handle a deletion request, or if we have exchanged emails and you want us to delete that exchange, write to support@imagostack.com from the address involved, stating:

The name of the application.
What information you want deleted.

We confirm receipt and resolve the request within a maximum of 30 calendar days. There is no charge for this.

Apps with an account

Bumko requires signing in with Google and stores in Google Firebase your profile (the name, email and photo provided by Google), your membership in a bar's team and the business data entered in the app.

Delete your account: from the app, in Settings → Delete my account, or by writing to support@imagostack.com from the email you use to sign in to Bumko. We delete your profile and your access to any bar.
If you are staff: the sales you recorded are the bar's records and stay with it, because they are part of its accounting. If you ask, we unlink them from your name and email.
If you are the bar's owner: deleting your account deletes the whole bar, with its products, sales, events and team. This cannot be undone.

Mallnest Business stores your account (email and name), the connection to your Shopify store and your shop's configuration. To delete everything, write to support@imagostack.com from your account's email: we delete the account, disconnect your store and your shop stops appearing in Mallnest. The Mallnest app for shoppers uses no account.

We handle requests by email within 30 calendar days at most, free of charge.

What we keep and for how long

Except for apps with an account, we do not keep user databases for our applications. For Bumko and Mallnest Business, we keep the data while your account, your bar or your store remains active, and delete it when you ask, as explained in the previous section. When you write to us, we keep the email exchange only for as long as it is useful to follow up on your enquiry, and then we delete it. If a legal, accounting or rights-defence obligation requires us to retain any data, we keep it only for the period that obligation imposes.
