Billkeep privacy policy

Last updated 12 October 2026

Billkeep is an invoicing app for small businesses. This policy explains what it stores, where, and what leaves your device. It is written to be read, not to be survived.

The short version

Your invoices, clients, tax rates and payment links are kept in a database on your own device, and a copy is stored in your Billkeep account so your phone and your browser show the same books. Billkeep needs an account to open, so this applies to everyone — there is no switch, and we would rather say so plainly here than leave you to discover it.

We do not sell your data and there are no adverts. We look at a count for each account, and at whether each of your devices is syncing — see what we count. We open your records only if you ask us to, by switching on support access. There is no tracking and no analytics SDK in this app.

What is on your device

Everything, and it works with no signal at all. This is the list a copy of which also goes to your account — see the copy in your account below:

It is never sold, never advertised against, and never opened by us unless you switch on support access. Nothing else about you is collected: there is no analytics SDK, no tracking and no third-party scripts anywhere in the app.

If you create an account

Accounts are handled by Firebase Authentication, a Google service. When you create one we receive and store:

This is used only to identify you so your records can follow you to another device. It is not used for marketing and is not shared with anyone.

The copy in your account

A copy of the records listed above is stored in Google Cloud Firestore under your account identifier, and it works in both directions: your changes go up within seconds, and changes you made on your other devices come back down onto this one.

This used to be a switch that started off, and it is not any more. The app asks everybody to create an account, and an account that then declined to carry your records to your own second device was a promise nobody had asked for and a source of real loss — people signed in on a laptop, saw an empty screen, and reasonably concluded their invoices had gone. It is on for every signed-in device now, on every plan, free included.

What we count

To see whether Billkeep is working for the people using it, and whether the free plan's monthly limit is set fairly, we count what is in the copy in your account. For each account the count gives us numbers and dates, nothing else:

The count reads only each record's type, status and dates. It never reads names, amounts, line items, addresses or payment details, and the device notes hold nothing from your records. All of it is kept next to the account's email address so we know which account it belongs to, and none of it is shared with anyone or used for advertising.

If you ask us for help

Billkeep has a switch, Let support see your account, under Help in the app and under Account on the website. It is off unless you turn it on.

When you contact us we may keep short notes next to your account: what you asked, and what we did about it. They are deleted when your account is deleted. Messages you send on WhatsApp or by email stay with those services; we do not copy them into Billkeep.

If you turn on voice invoicing

Voice invoicing is off by default. When you switch it on and use it, the words you say or type are sent to Google to be turned into a draft invoice.

Payments

Billkeep does not process payments and never handles your money or your customers' money.

You paste a payment link you already have — Stripe, PayPal, UPI, or anything else. Billkeep stores that link, prints it on your invoice as a button and a QR code, and opens it in your phone's browser when tapped. It has no payment processor, no webhook and no account with any provider, so it cannot see whether a payment happened. You record payments by hand.

Subscription payments for Billkeep itself are handled by Google Play. We never see your card details.

Billkeep on the web

This address runs Billkeep in your browser. It behaves the same way the phone app does, and for the same reasons:
