Contact: arnoldlabs.dev@gmail.com

1. Who is responsible

Arnold Labs is the controller of personal data processed through Invoice Pro, unless a law says otherwise.

2. Information we collect

Account: email address, user ID, authentication data from Firebase Authentication, and password hashes stored by the authentication provider (we do not store your raw password).

Business profile: company name, address, phone, business email, tax number, currency, payment instructions, terms, invoice template choice, logo, and signature images you upload.

Operational data: clients, products, invoices, quotations, recurring templates, payments (amount, method, status, date, reference, notes), expenses, and related documents you create.

Usage and device: app version, crash or diagnostic data if our tools collect it, and theme preference stored on device.

On-device security: PIN (stored as a one-way hash) and biometric preference stay on your device and are not uploaded to our servers.

We do not ask for your bank password or card PAN to process client payments. Payment methods you type (for example “M-Pesa”) are labels in your records only.

3. Why we process data

We process data to:

Legal bases (where GDPR or similar law applies) include: performance of a contract, legitimate interests (security, product improvement), consent where required, and legal obligation.

4. Where data is stored

Invoice Pro uses Google Firebase (Authentication, Cloud Firestore, Cloud Storage). Data may be stored and processed on servers outside your country, including facilities operated by Google. Google’s processing is subject to their terms and safeguards.

5. Sharing

We do not sell your personal data. We share data only with:

When you share a PDF, WhatsApp message, Gmail, or public view link with a client, you choose the channel. That third party’s terms apply. A public link is accessible to anyone who has the URL.

6. Retention

We keep account and business data while your account is active. If you delete your account in Settings, we delete your Invoice Pro documents and profile we control, then your authentication account, subject to backups and legal holds that may last a short additional period. On-device PIN data is cleared on that device when you delete or sign out according to the app’s design.

7. Your rights

Depending on your country, you may have rights to access, correct, delete, restrict, or port your data, and to object to certain processing. You can edit company and records inside the app, export report files from Reports, and delete your account in Settings.

To exercise rights or ask a question, email arnoldlabs.dev@gmail.com. You may also lodge a complaint with your local data protection authority.

8. Security

We use signed-in access, tenant-scoped data rules, and hashed device PINs. No method is 100% secure. Protect your password and device.

9. Children

Invoice Pro is for business use. It is not directed at children under 18. We do not knowingly collect data from children.

10. International users

If you access the Service from outside Kenya, you understand that your data may be transferred to and processed in other countries, including those that may have different data-protection laws.

11. Cookies and ads

The Android app does not use advertising cookies. The web app uses cookies or similar storage required for sign-in (Firebase Auth) and may use hosting/CDN cookies. We do not run third-party advertising.

12. Changes

We may update this Policy. The “Last updated” date will change. Material changes may be notified in the app. Continued use means you accept the updated Policy.

14. Additional privacy rights

We do not sell personal information and we do not share it for cross-context behavioural advertising. If a law such as GDPR, UK GDPR, or CCPA/CPRA applies to you, you may request access, correction, deletion, or a copy of personal data we hold, and you may appeal a refusal by emailing arnoldlabs.dev@gmail.com. We will not discriminate against you for exercising those rights.

15. Age

Invoice Pro is intended for people who can form a business contract (generally 18 or older). Do not create an account for a child.
