The dullest document is the most informative
BetterPicWhen deciding whether to upload fifteen photographs of your face somewhere, most people read the privacy policy. That is the second-best move.
Start with the list
The subprocessor list names the third-party companies that actually process your images. Shorter than the privacy policy, more concrete, and far harder to write vaguely — it is company names and countries rather than prose.
What it does and does not tell you
That such a list exists is normal. Nobody at this scale runs their own datacentres, so its existence is not a warning sign.
What informs you is how many names are on it and which jurisdictions they sit in.
Why this is a portrait question at all
Because generating a headshot means sending those fifteen images somewhere. The crop and the lighting are fixable later; what gets retained is not.
Then two words in the privacy policy
A retention period with a number in it. And the word training — not whether data is shared, which is a different question with a more comforting answer.
When it stops being your decision
The moment an employer uploads photographs of staff. Those are third parties' personal data, and consent sits with the employer.
