Privacy Policy
BlackInk (by CodeXpirit) · Last updated: August 1, 2026
BlackInk (“BlackInk”, “we”, “us”) is a mobile app that helps resellers track inventory, costs, sales, and profit. This policy explains what we collect, why, who we share it with, and the choices you have. By using BlackInk you agree to this policy.
1. Information we collect
Information you provide
- Account details — your name and email address, used to create and secure your account.
- Business data you enter — inventory/devices, purchase costs, sales, customer details you add to an invoice, and your business profile.
Information collected automatically
- Usage & analytics — how you interact with the app (screens viewed, features used), collected via Google Firebase Analytics.
- Diagnostics — crash reports and device state at the time of a crash, via Firebase Crashlytics, to keep the app stable.
- Identifiers — an app-instance identifier and, where applicable, an advertising identifier used by Firebase.
Payments
If you subscribe, payments are processed by Stripe. Your card details are entered into and handled by Stripe — BlackInk never sees or stores your full card number. We store only your subscription status.
2. How we use your information
- Provide the app’s core features (track inventory, costs, sales, profit, invoices).
- Create, authenticate, and secure your account.
- Send account-related emails (email verification, subscription confirmation).
- Process subscriptions and manage billing.
- Improve the app, fix crashes, and understand feature usage.
3. Service providers we share data with
We do not sell your personal data. We share it only with the providers that operate the app on our behalf:
| Provider | Purpose |
|---|---|
| Supabase | Account authentication and secure storage of your account and business data |
| Google Firebase | Analytics and crash reporting |
| Stripe | Subscription payments |
| Resend | Sending transactional emails |
These providers process data under their own privacy and security terms. We may also disclose information if required by law.
4. Data security
All data is encrypted in transit (HTTPS/TLS). Access to your business data is restricted to your authenticated account through database row-level security.
5. Data retention & deletion
We keep your data while your account is active. You can delete your account and all associated data at any time — in the app via More → Delete account, or by following https://legal.blackinkapp.com/delete-account. We may retain limited records where required by law (e.g. tax/accounting or payment records held by Stripe), and anonymized analytics that cannot identify you.
6. Children
BlackInk is not directed to children under 13 and we do not knowingly collect data from them.
7. Changes to this policy
We may update this policy from time to time. Material changes will be reflected by the “Last updated” date above.
