Vistoa tracks only the reading signals needed to run the product: article views, duration capped at 600 seconds, scroll depth, score-panel expansion, methodology clicks, traffic source, and device class.
We do not track mouse movement, heatmaps, paragraph-level dwell time, session replay, ad identifiers, or anything used for ad targeting. Reading events are not sold, shared with outlets, or sent to third parties.
You can disable reading history in account settings, export your reading data as JSON, and delete your account data. Account deletion cascades through preferences, reading events, tracked stories, saved searches, and daily brief records.
Email unsubscribe is honored immediately. Daily brief sends are stored with their payload only for debugging, deduplication, and deliverability review.
