A little company, on Android.

Bring your gift with you

After installing or updating, return to the original gift page or open the complete private continuation link you copied. Google Play’s Open button alone cannot restore a private gift key.

If a link stays in your browser, open Android Settings → Apps → Dear Mori → Open by default and enable supported links. Then return to your original page and tap Open in Dear Mori.

On another device, keep the complete private link. Never post it publicly.
