> How Vinaka Apps handles data in the Invoice Custom Fields app.

Last updated: March 26, 2026

## 1. Who we are

This Privacy Policy explains how **Vinaka Apps** ("we", "us", "our") processes data when you use the Invoice Custom Fields app (the "App").

Contact: [support@vinaka-apps.com](mailto:support@vinaka-apps.com)

## 2. Scope

This policy applies to data processed through:

* the Stripe app UI,
* backend API endpoints used by the app,
* Stripe webhook processing.

## 3. Data categories we process

### Tenant configuration data

* Stripe account ID,
* sandbox/live indicator,
* field mapping rules,
* app enabled/disabled state,
* billing linkage fields (customer/subscription status references).

### Activity log data

* Invoice ID,
* action performed (auto-fill, finalize),
* actor type (webhook, dashboard user),
* sync status and technical error detail,
* timestamps.

### Invoice data (read-only from Stripe)

* Invoice metadata,
* customer metadata,
* Checkout session custom fields,
* invoice custom fields (current state).

This data is read from Stripe at the time of sync and is not stored permanently.

## 4. Data usage purposes

We process data to:

* configure and run invoice custom field mapping,
* prevent duplicate processing via idempotency,
* expose validation and sync status in Stripe,
* enforce billing/subscription rules,
* secure and monitor the service.

## 5. Data sharing

We share data only with required service providers, including:

* Stripe,
* hosting/database infrastructure providers.

We do not sell personal data.

## 6. Retention

We keep operational records only as long as needed for service operation, reliability, support, and legal/accounting obligations.

Deletion requests can be sent to [support@vinaka-apps.com](mailto:support@vinaka-apps.com).

## 7. Security

We apply reasonable technical and organizational measures to protect data in transit and at rest.

No system can guarantee absolute security.

## 8. Your rights

Depending on your jurisdiction, you may have rights to access, rectify, erase, restrict, object, or request portability.

Contact us to exercise rights: [support@vinaka-apps.com](mailto:support@vinaka-apps.com)

## 9. Changes

We may update this Privacy Policy. The current version is published on this page.
