Doc GenPrivacy policy
Last updated: 11 November 2026
Leon Digital ("we", "us") makes Doc Gen, an app for creating quotations, invoices, receipts, credit notes, debit notes and refund notes. This policy explains how Doc Gen handles your information and how you can contact us about it.
Your business records stay on your device
Your business profile, customer records, documents, payment records, and generated PDFs are stored on your device. We do not receive, see or store them.
They leave your device only when you choose:
- Sharing or printing a PDF hands it to the app or printer you pick.
- Backups are files you save or share yourself (for example to your Downloads folder, Google Drive or email). Backups are not encrypted, so keep them somewhere private.
Your account (optional)
Signing in is optional; without it, Doc Gen works fully offline and we receive no account information.
If you sign in, with Google sign-in or a sign-in link or one-time code sent by email, we store your email address and an account ID so we can recognise your account. This is handled by Supabase, our backend provider, in its Singapore region, and by Google if you use Google sign-in.
We do not sell your personal data.
Deleting your account
- In the app: open the menu → Account → Delete account, type "delete account" and confirm. If your last sign-in was more than 10 minutes ago, you confirm it's you by signing in again first.
- On the web: sign in with Google at https://docgen.leondigital.fyi/delete-account.html and confirm.
- By email: write to us from the address linked to your account. We delete the account within 30 days and reply to confirm.
In the app and on the web, your account and its associated data are deleted immediately and cannot be recovered.
Deleting your account does not delete the business records on your device; uninstalling the app does (backups you saved elsewhere are not affected).
Notifications
If you turn on payment due reminders, Doc Gen schedules notifications on your phone from your own invoices. They are created on the device; nothing about them is sent to us.
Purchases
Remove Ads and the Premium Designs pack are one-time purchases through Google Play, and buying needs a Doc Gen account. Google handles the payment; we never see your card or payment details. So that a purchase belongs to your account and follows it to any phone, we check it with Google and store, with your account ID: which product you bought, Google's order number and purchase token, and the purchase date. This is deleted with your account. Your device also remembers your purchases so they work offline.
Ads
The free version shows ads from Google AdMob: a banner at the bottom of the main screens and, after you issue a document, at most one full-screen ad. To show and measure ads and prevent fraud, Google's Mobile Ads SDK collects your device's advertising ID, approximate location derived from your IP address, and information about ad interactions and app performance, and shares it with Google. Google's policy: https://policies.google.com/technologies/ads
Where the law requires it (for example in the EEA and UK) you are asked for consent first, and you can change your choice in Settings → Ad privacy choices. You can reset your advertising ID or opt out of personalised ads in your phone's settings (Settings → Google → Ads, or Privacy → Ads).
Features not yet in the app
Upgrades bought through Google Play (including removing ads) and crash reporting are planned but not active in the current version, and the app does not collect data for them. Before either is introduced we will update this policy to describe what it collects and why.
Your rights
You may ask to access or correct the personal data we hold about you, or withdraw your consent, by contacting us at the address below.
Security
Data sent to our backend is encrypted in transit (HTTPS). Access to account data is restricted so each account can only read its own records.
Third-party services
- Supabase (accounts): https://supabase.com/privacy
- Google (Google sign-in and AdMob ads): https://policies.google.com/privacy
Children
Doc Gen is a business tool and is not directed at children under 13. We do not knowingly collect information from children.
Changes
We will update this page when the app's data practices change and change the "Last updated" date above.
