Grammarly
ParentMode's take
13+ with parental awareness; 16+ for independent use
Grammarly is fundamentally a writing-assistance tool with a legitimate educational purpose, but it uses AI to process text—including potentially sensitive content—and stores writing data. The maturity threshold depends on whether a child can understand that their writing may be retained and used to improve the service.

What a parent can do
Data & privacy
Check the app's privacy label in the App Store; assume any text submitted to Grammarly may be retained or used to train its AI models, even if the user account is young.
Controls
Use device-level Screen Time (iOS) or Family Link (Android) to set app time limits and restrict where Grammarly can be used; review the app's own account settings to understand data retention options.
A cautious next step
For younger writers, offline or school-provided grammar tools that don't transmit writing to cloud AI systems may carry fewer data considerations.
