Privacy Policy

Last updated: July 19, 2026

InvoiceFast (“we”, “us”) helps you create invoices and estimates. This policy explains what we collect, how we use it, and the choices you have. InvoiceFast is local-first: your data lives on your device, and is backed up to our servers only to sync it across your devices.

Information we collect

• Account. You can sign in with Apple, Google, or your email address. We receive a stable user identifier and, where available, your name and email. If you sign in with email, we use your address to send you a one-time sign-in code — there is no password anywhere. When you sign in with more than one method using the same verified email, we treat them as a single account.
• Your business content. Business details, clients, rate-book items, invoices and estimates you create — including any line items, notes, photos, and signatures you add.
• Usage. A small, deliberate set of in-app events (for example, creating a document or reaching the subscription screen), linked to your account identifier, so we can understand how the app is used and improve it. This is first-party product analytics — it is not used for advertising and is not shared with advertisers.
• Diagnostics. Aggregated, non-identifying crash and error reports to keep the app reliable. These never include your invoices, tokens, or personal content.

We do not collect your location, contacts, or advertising identifiers, and we do not use tracking for advertising.

How we use your information

• To provide the app: creating documents, and backing up and syncing them across your devices.
• To authenticate you when you sign in.
• To understand how the app is used so we can improve it (first-party product analytics).
• To maintain, secure, and improve the service.

Payments

Subscriptions purchased in the mobile app are processed by Apple or Google. Subscriptions purchased on our website are processed by Paddle, which acts as merchant of record and handles payment, tax, receipts, renewals, and cancellations. We never receive or store your full payment card details.

Storage, security & sharing

Your synced content is transmitted over encrypted connections (TLS) and stored on our servers. Your session credential is stored securely on your device. We do not sell your data or share it with advertisers. We share data only with the service providers that help us run InvoiceFast, and only as needed to operate the service or where required by law. These include Apple and Google (sign-in), Postmark (sending email sign-in codes), RevenueCat, Paddle, and the app stores (subscription management and billing), Cloudflare (image storage), PostHog and Sentry (product analytics and crash diagnostics), and our hosting provider.

Data retention & deletion

We keep your synced data until you delete it. You can permanently delete your account and all synced data at any time from within the app: Settings → Account → Delete Account. This removes your account and associated invoices, estimates, clients, rate-book items and backups from our servers, and signs you out of every device. To prevent abuse of our free tier, we retain a one-way cryptographic hash of a deleted account’s sign-in identifiers for 30 days — it cannot be used to identify you and is deleted automatically. You can also export your invoices and clients as CSV at any time from Settings.

Your rights

Depending on where you live, you may have the right to access, correct, export, or delete your personal data. You can exercise access, export and deletion directly in the app, or contact us at hello@invoicefastpro.com.

Children

InvoiceFast is intended for businesses and is not directed to children under 13. We do not knowingly collect personal information from children.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by updating the date above and, where appropriate, through in-app notice.
