Tap +, tap a day on your calendar, or describe the event in the Ask bar in plain language ("dentist Tuesday at 3").
Go to Profile → API Keys and add a key from an AI company, then pick your models in Profile → AI Features. Chat also works without a key, using our backup provider.
Not yet. You can import a calendar file (.ics, or Google, Outlook or Notion exports) in Profile → Import & Export, and add any GYST event to Google Calendar from the event's menu.
Go to Profile → Friends & Family, invite someone with your link, then form a family group or share individual events and lists.
If you can still read your account's email, choose Email me a code on the unlock screen. If you lost both, email [email protected] from an address you can read. We'll check details your account already had, including having you sign in with your password. Then we email your account's current address and wait 72 hours before turning Protect your GYST off, and moving your account to your new email if you ask. We never do this sooner or without that email. Unlocking with your passkey or a code during the 72 hours cancels it. If you don't know your password either, we can't verify the account.
Profile → Import & Export → Export. You get a file with your events, tasks, people, routines, lists, habits, Apple Health data, reminders and settings. For Money data, email [email protected].
Profile → Delete Account (at the bottom, under Log Out), on iPhone or the web. You'll type DELETE and confirm it's you with a passkey or an emailed code. Everything is deleted right away, banks and connected services are disconnected, and we email you a confirmation. It can't be undone, so export first if you want a copy.
In Money, open the bank's connection card and choose Unlink. Its accounts and transactions are deleted from GYST and we ask Plaid to revoke access. To withdraw your Money consent entirely (every bank and everything in Money at once), go to Profile → Security → Money → Disconnect banks & withdraw consent (also at the bottom of Money → Connections). This deletes everything in Money, including your budgets and the assets you added. You'll confirm it's you, see exactly what will be deleted, and confirm once more. You can also email [email protected].
Profile → Security → Connected Agents, then Disconnect. Access stops immediately.
To keep it out of AI: Profile → AI Features → turn off Include Apple Health data (it's off unless you turned it on). To delete it: Profile → Apple Health → Delete Apple Health data from GYST. To stop GYST reading it: the iPhone Health app → your profile → Apps → GYST.
iPhone: Settings → Privacy & Security → Location Services → GYST. GYST uses location only for place reminders, and your movements never leave your phone.
Profile → Gmail → Disconnect. GYST revokes its access at Google and deletes its tokens.
If you think you've found a vulnerability in GYST, email [email protected] with the details and how to reproduce it. Please don't access other people's data or disrupt the service while testing, and give us a reasonable time to fix the issue before sharing it. We'll acknowledge your report within a few business days. Our contact details are also in security.txt.
