Billing and subscription support

Sen Kasa Pro subscriptions may be billed through Apple, Google, or Stripe — or may be complimentary. Support routes depend on your billing source:

Apple App Store

Manage or cancel: App Store → your account → Subscriptions → Sen Kasa.
Refunds: reportaproblem.apple.com. Refunds are handled by Apple under its own policies; we cannot issue App Store refunds.
Billing questions: Apple billing support or contact support@senkasa.com for guidance on what to tell Apple.
Purchase not recognised in the app: use the Restore purchases button in the app. If the problem persists, contact support@senkasa.com with your account email.

Google Play

Manage or cancel: Google Play Store → Payments & subscriptions → Subscriptions → Sen Kasa.
Refunds: follow Google Play's refund process. Refunds are handled by Google; we cannot issue Play refunds.
Billing questions: Google Play billing help or contact support@senkasa.com.
Purchase not recognised in the app: use the Restore purchases button in the app. If the problem persists, contact support@senkasa.com with your account email.

Stripe (website purchase)

Manage or cancel: sign into your Sen Kasa account on the website, open the Subscription page, and select Manage billing. This opens the Stripe Customer Portal where you can update payment methods, view invoices, and cancel.
Refunds and billing disputes: contact support@senkasa.com. Website-billed refunds are processed through Stripe by us.
Payment failed or access not active: check your subscription status on the website. If payment processing is delayed (e.g., after a failed payment retry), your access may temporarily show a grace period. Contact support@senkasa.com if the issue persists beyond 72 hours.

Complimentary access

Complimentary Sen Kasa Pro access is granted at our discretion and may be time-limited or revoked. There is no billing management, cancellation, or refund option.
If your complimentary access unexpectedly stops working, contact support@senkasa.com.

Before contacting us

Include app version, device model, operating-system version, language, approximate time of the problem, and a description of what you expected and what happened. For subscription issues, include your account email (do not send passwords). For EET testing, include the environment (Playground/Testing) and the displayed error code. Do not send certificates, .p12 files, certificate passwords, bearer tokens, payment-card data, signed fiscal XML, receipt lines, or customer/staff data.

Urgent incident

If you believe credentials, a certificate, token, or customer information was exposed, or if you suspect an account takeover or entitlement fraud:

Stop using the affected credential immediately.
Revoke or rotate it with the relevant issuer/provider (certificate authority, Apple, Google, or Stripe). Revoke an affected Sen Kasa device in the account portal.
If your Sen Kasa account may be compromised, change your password and enable multi-factor authentication if available.
Preserve only non-sensitive diagnostic details.
Email security@senkasa.com with subject "Security incident".

Sen Kasa does not provide emergency fiscal, payment, or legal support in this early-access release.

Data deletion

To delete your Sen Kasa account and associated Sen Kasa-controlled data (merchant profile, staff records, device registrations, entitlement history, and managed backup snapshots), sign into the website portal and use the account deletion option, or email privacy@senkasa.com with subject "Account deletion request". This does not delete local app data, exported files, or data controlled independently by Apple, Google, Stripe, or another integration provider. To request access to or deletion of a specific managed backup, email privacy@senkasa.com with "Privacy deletion request" and its account/reference details.
