Privacy Policy

NailBid ("NailBid", "we", "us") is a quoting and invoicing app built for tradespeople and small construction businesses, available worldwide with support for currencies across Europe, the Americas and Africa. This policy explains what data NailBid handles, how it's stored, and what — if anything — leaves your device.

1. What NailBid stores, and where

When you use NailBid, the following is saved in a local database on your device only:

• Your business profile — business name, phone number, email address, VAT number, and default tax/payment settings.
• Customer records you create — name, phone, email, address, and any notes you add.
• Quotes and invoices you create, including line items, prices, and status.
• Your app preferences — theme (light/dark), and whether you have an active NailBid Pro subscription.

None of this is transmitted to NailBid or to any server we operate — because no such server exists. It stays on your device, in the app's private storage, for as long as the app is installed. Uninstalling NailBid, or losing or resetting your device without a backup, permanently deletes this data — NailBid does not provide cloud backup, so we cannot recover it for you.

2. Sharing quotes and invoices

When you export a quote or invoice as a PDF and share it — by email, messaging app, or any other method — that action is entirely yours: you choose the recipient and the method through your device's own share sheet. NailBid does not send this document anywhere on your behalf, and does not keep a copy of what you shared or who you shared it with.

Similarly, the "Email", "Call" and "View address" actions on a customer's page simply hand off to your device's Mail, Phone, or Maps app with that customer's own details already entered — NailBid does not record that you took that action.

3. NailBid Pro purchases

NailBid Pro (monthly, yearly, or lifetime) is sold as an in-app purchase through the Apple App Store or Google Play, and purchase validation is handled by our subscription provider, RevenueCat. To activate and verify your purchase, the following is shared with Apple/Google and RevenueCat:

• A randomly-generated app user identifier (not your name or email — NailBid doesn't ask for either to make a purchase).
• Purchase and subscription status (product purchased, renewal date, whether it's active).
• Basic device and app information Apple/Google/RevenueCat require to process any in-app purchase (e.g. device type, app version).

We never see your card details — those are handled entirely by Apple or Google. See RevenueCat's own privacy policy for how they handle this data.

4. PIN and biometric lock

NailBid offers an optional PIN lock and Face ID / Touch ID unlock (Settings → Security). If you turn this on:

• Your PIN is never stored as plain text — only a one-way cryptographic hash of it is saved, on your device, using iOS's Secure Enclave-backed Keychain (via expo-secure-store).
• Face ID / Touch ID authentication is handled entirely by your device's operating system — NailBid never sees or stores your biometric data itself, only a yes/no result from the OS.
• None of this — your PIN hash, biometric results, or lock/attempt history — ever leaves your device.

5. What NailBid does not do

• No analytics or tracking SDKs of any kind are built into the app.
• No advertising, and no ad networks.
• No account or sign-in is required to use the app.
• We do not sell, rent, or share your business or customer data — we don't have it to begin with.

6. Your data, your control

Because your business and customer data lives only on your device, you are always in control of it: edit or delete any customer, quote, or invoice directly in the app at any time, or remove all of it at once by uninstalling the app. There is no NailBid account or server-side record for us to delete on your behalf, because none exists.

7. Children's privacy

NailBid is a business tool intended for tradespeople and is not directed at children. We do not knowingly collect information from children under 13 (or the relevant minimum age where you live, if higher).

8. App Store / Play Store privacy labels

Apple and Google both require a short, structured summary of what an app collects, shown on the app's store listing before you install it. For NailBid, that summary is:

• Purchases (purchase history) — linked to your anonymous app user identifier, used only to activate and verify NailBid Pro. Not used for tracking.
• Identifiers (the anonymous app user identifier itself) — linked to you in the sense above, used only for the same purpose. Not used for tracking.

Everything else described in this policy — your business, customer, quote and invoice data, your PIN, and your app preferences — is not collected under Apple's or Google's definitions, because it never leaves your device. NailBid does not use any analytics, advertising, or tracking SDKs, and does not share data with data brokers or for cross-app/cross-site advertising purposes.

9. Changes to this policy

If NailBid's data practices change — for example, if we ever introduce an optional cloud sync feature — this page will be updated with a new "last updated" date before that feature ships, and, where required, we'll ask for your consent first.
