Privacy Policy

Last updated: September 25, 2026

1. Overview

We collect only what we need to sign you in, let you add credit, connect your calls, and keep the Service secure. We do not sell your personal information, and we do not record your calls.

2. What we collect

Account information. Your mobile phone number, which you use to sign in and which we verify with a one-time code.
Wallet and payment information. Your calling-credit balance and a record of your top-ups. Card payments are processed by Stripe; we receive confirmation of a payment and limited details (such as amount and status) but never your full card number.
Call records. For each call you place, we keep the number dialed, the date and time, the length of the call, and its cost — this is what lets us bill you accurately and show your history.
Technical and log data. Basic information needed to operate and protect the Service, such as app activity and diagnostic logs.

Device permissions. The app asks for a few permissions, each used only for calling: the microphone (to carry your voice during a call), phone status (to pause your Kalisstar call if a regular phone call comes in; this is checked on your device and not sent to us), notifications (to show that a call is in progress), and optionally your contacts (see below).

3. Your contacts stay on your device

If you give the app permission to access your contacts, it reads them on your device so you can dial someone by name. Your contact list is not uploaded to or stored on our servers. You can turn this permission off at any time in your device settings; the app still works, you'll just type numbers manually.

4. How we use your information

To create and secure your account and verify your phone number;
To add calling credit and bill you for connected calls;
To connect your calls to the person you're dialing;
To provide customer support;
To detect, prevent, and investigate fraud, abuse, and security issues; and
To meet our legal and regulatory obligations.

5. Call content

Kalisstar does not record or listen to the audio of your calls. We keep only the call details described above (number, time, duration, cost) for billing and support.

We share information with a small set of service providers who help us run Kalisstar, and only as needed:

Google Firebase — to verify your phone number, confirm that requests come from the genuine Kalisstar app, and sign you in.
Stripe — to process your payments securely.
Africa's Talking — the licensed carrier that connects your calls to Nigerian phone networks.
Supabase, Railway, and DigitalOcean — to host our database, backend systems, and the call-routing servers that connect your calls.

We may also disclose information if required by law, to respond to lawful requests, or to protect the rights, safety, and security of our users, the public, or Kalisstar. We do not sell your personal information.

7. How long we keep it

We keep your account information and call records while your account is active. When you delete your account, we remove your phone number and sign-in identity and disable calling right away (see section 10). We keep records of past payments, wallet transactions, and calls (date, duration, cost, and number dialed) after deletion, no longer linked to your phone number, for as long as needed to meet accounting, tax, fraud-prevention, and legal obligations. Routine backups of our systems may contain your information for a limited time before they are overwritten.

8. Security

We use technical and organizational measures to protect your information, including encrypted connections and restricted access to our systems. No method of transmission or storage is completely secure, but we work to protect your data and to respond promptly if an issue arises.

9. Your choices and rights

You can ask us to access, correct, or delete your personal information, and depending on where you live you may have additional rights under laws such as US state privacy laws or Canadian privacy law. You can delete your account yourself at any time in the app (see section 10). For other requests, email support@kalisstar.com and include the mobile number on your Kalisstar account so we can verify it's you. We won't discriminate against you for exercising these rights.

10. Deleting your account

You can delete your Kalisstar account at any time in the app under Settings → Delete account. We'll send a one-time code to your number to confirm it's you. You can also ask us to delete it by email. Full steps are on our account deletion page.

When your account is deleted:

Your phone number and sign-in identity are removed, and your account can no longer sign in or place calls;
Any calling credit left in your wallet is forfeited, so request a refund of unused credit before deleting (see our Refunds & Disputes Policy); and
Records of past payments, transactions, and calls are kept as described in section 7, no longer linked to your phone number.

If you sign up again later with the same number, you'll start with a new, empty account.

11. Children

Kalisstar is not intended for anyone under 18, and we do not knowingly collect information from children. If you believe a child has provided us information, contact us and we'll delete it.

12. Where your data is processed

Kalisstar is operated from the United States, and your information is processed and stored on servers located in the United States. Connecting your calls also involves our carrier partner operating in Nigeria. By using the Service, you understand your information will be handled in these locations.

13. Changes

We may update this Policy from time to time. We'll change the date above and, for material changes, notify you in the app where appropriate.
