The reward

A qualifying invitation gives the inviter 20 SunDrops and the invited learner 10 SunDrops. No purchase, Play installation, review, rating or positive feedback is required. SunDrops have no cash value, cannot be withdrawn or transferred, and work only for eligible HoiDutch extras. Existing SunDrop debt from a reversed purchase is settled first.

How to qualify

1. Both people must have verified adult accounts. Share your link only with someone who wants it.
2. A new learner enters the code within seven days of creating their account. Each account can use one invite. Self-referrals and repeated use of an email address are excluded.
3. After entering the code, the learner opens and completes at least three different curriculum lessons across three separate server-recorded study days. At least 72 hours must pass after using the code. Imported completion lists alone do not satisfy the separate study-day requirement.
4. The learner selects Check my reward within 30 days of using the code. Qualifying credits are added to both accounts together, once. Both accounts must still exist and remain eligible.

Alpha limits

Each inviter can have five accepted invitations during the 120-day offer window. Pending invitations count toward this limit. The app-wide budget is 3,000 credited SunDrops per UTC calendar month. When this budget is full, no credit is issued; the learner may check again in the next month if still within the 30-day qualification window. Limits are shown before participation. This is a limited alpha offer; future offers may differ. We will not require reviews or purchases to qualify.

Privacy and fairness

The app does not read your contacts or send invitations automatically. The shared link contains a random code, not your email. The inviter sees aggregate invitation/reward counts, not the other person's email, lesson answers or identity.

We store the referral relationship, times, reward status and server-recorded lesson activity needed to administer the offer. A keyed email fingerprint helps prevent delete-and-register abuse and common Gmail aliases; it is pseudonymous personal data, not anonymous data. Referral claim records expire after 120 days and are purged on routine authenticated activity or restart. The fingerprint and referral accounting record can remain after account deletion until that purge; account identifiers are detached on deletion. Wallet records follow the retention described in the privacy policy. We rely on the requested offer and the legitimate interest of preventing reward fraud; contact us with a privacy objection or dispute.

Account export includes your referral status and times without exposing the other person's identity. Contact kash@thekashe.world for reward or privacy questions. See the privacy policy.
