Account and Data Deletion

App: Calc 3D (com.calc3d.nativeapp) · Axiom 3D Studio · Last updated: August 27, 2026

This page explains how to delete your Calc 3D account and the data associated with it. You can do most of it yourself, inside the app, without asking anyone. For what depends on us, there is an email request described in section 3.

1. What you can delete yourself, right now

Calc 3D keeps your data on your own device and, if you turned backup on, in your own Google Drive account. In both cases you are in control:

1.1 Erase everything on the device

Open the app
Go to Settings
Tap Reset All

This erases quotes, sales, orders, schedule, history, printers, materials and settings. It is immediate and cannot be undone.

1.2 Disconnect your Google account

In Settings → Google Drive Sync, tap disconnect

The app loses access to your account and stops sending backups.

1.3 Delete the backup file in your Drive

The backup lives in a reserved area of your Google Drive that only the app can access. To remove it permanently:

Go to myaccount.google.com/permissions
Select Calc 3D
Tap Remove access

Removing access deletes the data the app stored in that area. Doing this from Google's website works even if you have already uninstalled the app.

1.4 Uninstall the app

Uninstalling erases everything that was on the device. It does not erase the Drive backup or the records described in section 2 — for those, follow steps 1.3 and 3.

2. What stays with us, and can be deleted on request

Outside your device and your Drive, we keep very few records. All of them can be deleted at your request:

Record	What it contains	Why it exists
Authentication account	Your Google email, name and profile picture	To identify you when you sign in to the app
Pro entitlement	Purchase identifier and the email tied to it	To recognise your purchase on a new device and detect refunds
Coupon use	Code used and purchase amount — only if you used a referral coupon	To calculate the referring partner's commission
Notification address	A device identifier generated by Google, without your name or email	To send app notices and purchase re-checks

We do not keep your quotes, sales, clients, orders, prices or any data about your business. None of it leaves your device and your Drive — not to us, not to third parties.

3. How to request deletion

Send an email to axiomcalculator3d@gmail.com with the subject Account deletion and tell us:

The Google account email you use in the app

That is all. The request must come from the address to be deleted — that is how we confirm it is you, without asking for any other document.

Timing: we confirm receipt within 7 days and complete the deletion within 30 days of the request.

If you prefer, we also answer at @axiom_3d_studio on Instagram — but in that case we will ask you to confirm by email, so we can be sure the request came from you.

4. What we cannot delete

Your Google Play purchase history. That record belongs to Google, not to us. To handle it, use myaccount.google.com or contact Google Play support.
Purchase records required by law. Where a purchase exists, the corresponding record may need to be kept for the period required by tax and consumer protection law, even after the account is deleted. During that period the record is archived and used for nothing other than meeting that obligation.
Backups already deleted. Once you remove the app's access to your Drive, the file is outside your control and ours — neither party can recover it.

5. Does deleting my account remove my Pro purchase?

The purchase stays tied to your Google Play account. If you delete your data here and later install the app again with the same account, Pro is restored normally — you do not have to buy it again.

If what you want is a refund, that is handled by Google Play, not by this page. See the Google Play refund policy.
