Follow-ups are intentionally limited so the focus stays on your own thinking. A JOURNAL THAT REMEMBERS Dayheld can organize themes and meaningful details from your entries, help you ask questions across time, and create weekly and monthly perspectives. You can see, correct, or delete what Dayheld remembers. PRIVATE BY DESIGN Journal records are encrypted on your device. Dayheld is covered in the app switcher, and you can lock it with Face ID, Touch ID, or your passcode. Dayheld does not automatically upload or sync audio; only an export you explicitly share can carry retained audio elsewhere. If you enable iCloud sync, encrypted journal data—not audio—syncs through your private CloudKit database. After you allow AI, direct features and due scheduled insights or Life in Review may send selected readable journal-derived text through Dayheld’s Cloudflare-hosted proxy to OpenAI. Audio is never sent to AI. Provider handling and retention may apply; full details are in the Privacy Policy.
