What are your favorite non-foss apps?

Letterboxd is a social platform for sharing your taste in film. Use it as a diary to record your opinion about films as you watch them, or just to keep track of films you’ve seen in the past. Rate, review and tag films as you add them. Find and follow your friends to see what they’re enjoying. Keep a watchlist of films you’d like to see, and create lists/collections on any topic.
Are they ethical though? (Serious question as I’m uninformed)
Both are directly tracking what you watch/read so I would worry that they might sell this data to others.
