That is the report most worth sending, and it will be acted on. Include the name, the script, and what it should have been. Being wrong about somebody's name in their own script is the error this app most wants to avoid.
Some renders are wrong on purpose, in the sense that they are conventional rather than exact. Twenty of the sixty-five cards say “by convention” and name the convention they follow — Arabic and Hebrew leave out your short vowels, Tamil does not write the difference between p and b, Chinese picks characters that mean something. Those are not bugs.
Correct, and deliberate. Linear A and Cypro-Minoan cannot be read by anybody. Cherokee has no letter for a lot of English sounds. Khipu is knotted cord rather than writing. A SignWriting name sign is given by a Deaf community, not generated. Each of those cards explains itself.
Lastscript makes no network requests at all. There is no account, no analytics, and no server. Your name is stored on your own device so the app and its widget can show it, and nothing leaves the phone. Nothing is collected, so there is nothing to request or delete beyond deleting the app.
Letterforms are from the Noto project under the SIL Open Font License 1.1. The script inventory comes from ISO 15924 and the Unicode Character Database. The narrative and the transliteration tables were written for this app.
