HiNoter Privacy Policy (hinoter.com/privacy-policy)

HiNoter, which publishes the HiNoter app, 2026

Read on October 22, 2026

What it is: The privacy policy of HiNoter, last updated on 8 October 2026. It gives a seven-day period for deleting an account's data after a deletion request, says AI prompts and processing data are not kept longer than necessary, and names Microsoft Azure OpenAI Service as the AI processor.
How much weight it carries: The company's own policy, read in full for its retention sentences. It sets no fixed period for recordings or transcripts and does not say whether people review them. Its statement that access is limited to employees with a reasonable need is an access rule, not a review rule, so it is not recorded as one.
