Privacy Policy
Last updated: October 13, 2026
1. Information We Collect
TellySynco collects information you provide directly — such as your name, email address, and family member profiles — as well as information generated through your use of the service, including calendar events, tasks, habits and their completion history, shopping lists, meal plans, allowances and transactions, messages you send to the Synco assistant, and household preferences. We also record the devices you sign in from so we can deliver notifications.
On iPhone, and only if you switch it on yourself, we additionally read a limited set of Apple Health data. Section 5 sets out exactly what we read, what we write back, and what does and does not leave your device.
2. How We Use Your Information
We use your information to provide, maintain, and improve TellySynco's services, including AI-powered scheduling, task management, and family coordination features. We do not sell your personal information to third parties.
Synco AI. When you ask the Synco assistant a question, we send your message and what's needed to answer it — your household's event and task titles and member names — to Google Gemini, our AI provider, solely to generate a reply. We never send your password, payment information, or Apple Health data to Gemini. The iOS app asks your permission before your first message is sent this way.
3. Data Storage & Security
Your data is stored securely using industry-standard encryption. We use Firebase and Google Cloud Platform infrastructure with strict access controls to protect your family's information.
4. Calendar Connections (Google, Microsoft Outlook, Apple)
TellySynco can connect to your existing calendars so your household's shared dashboard shows what is already on them. Connecting is entirely optional, is off until you start it yourself, and each connection is made by one member for their own account. If you never connect a calendar, nothing in this section applies to you.
Google Calendar — exactly what we ask for. When you connect a Google account, Google shows you a consent screen listing the following permissions. We request these four and nothing else:
- Your email address (
userinfo.email) — used as the label for the connection, so that when several family members each connect their own Google account you can tell them apart and we keep their calendars separate. - The list of calendars you are subscribed to (
calendar.calendarlist.readonly) — used only to show you that list so you can tick which calendars to display and which to leave out. We read the list of calendars, not their contents, at this step. - Events on your calendars (
calendar.events.readonly) — used to read events from the calendars you ticked, so they appear on your household dashboard and stay up to date when you change them in Google Calendar. - Permission to add and change events (
calendar.events) — used in two places, both of which you trigger: when you confirm a draft event that Synco read from a photo of a school notice or schedule, we add it to the Google calendar you chose; and when you edit or delete a TellySynco event from inside the app, we apply the same change in Google Calendar so the two do not disagree.
We do not request permission to see or download whole calendars beyond the events on them, and we do not request access to Gmail, Drive, Contacts, or any other Google service.
What we store, and where. Events from the calendars you selected are copied into your household's record on our servers, alongside the provider's own identifier for each event, so that the dashboard works without re-contacting Google on every screen and so a later change in Google can be matched to the right event. This is a stored copy, not a temporary one. The access and refresh credentials Google issues us are encrypted with AES-256-GCM before they are written to our database, using a key held outside it.
Google Limited Use. TellySynco's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Specifically: we use Google user data only to provide and improve the household calendar features described above; we do not transfer it to others except as necessary to provide those features, to comply with applicable law, or as part of a merger or acquisition; we do not use it for serving advertising of any kind; and we do not allow humans to read it, except with your explicit consent for specific items, where it is necessary for security purposes or to comply with applicable law, or where the data has been aggregated and de-identified.
What we never do with it. We do not sell your calendar data. We do not share it with data brokers or advertising networks. We do not use it, or anything derived from it, to train machine-learning or AI models. Calendar contents are not sent to our AI provider except for the specific text you yourself submit to the Synco assistant, as described in Section 2.
Disconnecting, and how to revoke access at Google. You can disconnect a calendar at any time from Settings → Calendar Accounts inside TellySynco. Disconnecting immediately stops all further reading and writing, tells Google to withdraw the access you granted us, and deletes the stored credentials from our database. We cannot reach your calendar again unless you connect it a second time and grant consent afresh. The events already imported are hidden from your household's screens but kept, so that reconnecting the same account restores your calendar without setting it up again; to have that stored copy erased instead, delete your account as described in Section 7, or email us using the address in Section 9 and we will delete it for you. You can also confirm or withdraw our access independently at your Google Account's third-party access page, which is Google's own record of which applications you have authorised.
Microsoft Outlook and Apple Calendar. Outlook connections work the same way and are subject to the same storage, retention and deletion rules set out above. Apple Calendar is read on your device through Apple's EventKit with your permission, and the events you choose to share are stored with us on the same terms.
5. Apple Health (iPhone only)
TellySynco's iPhone app can connect to Apple Health so that habits you track here tick themselves off from activity you have already recorded, instead of you logging it twice. This is entirely optional and is off until you turn it on in the app's Settings and grant permission in Apple's own dialog. If you never connect it, nothing in this section applies to you.
What we ask permission to read. Step count, walking and running distance, active energy burned, exercise minutes, mindful minutes, sleep analysis, water intake, and body mass. We ask for nothing else, and we do not read medical records, clinical data, or any health category outside that list.
What we write back. When you complete a matching habit inside TellySynco, we can save that completion into Apple Health as water intake, a mindful session, or a workout, so your progress sits alongside the rest of your activity. Those three are the only things we ever write.
What leaves your iPhone. We do not upload your Apple Health records. Reading happens on your device. For each habit you have explicitly linked to a Health metric — and only for those — the app sends our servers three things per day: the date, that day's total converted into the habit's own unit (for example “8,412 steps”), and Apple Health's identifier for the sample it was derived from, which we use solely to avoid counting the same activity twice. That figure is stored with the rest of your habit history and is marked as having come from Apple Health rather than from you tapping. Health metrics you have not linked to a habit are never sent to us, and we never receive the underlying samples, timestamps, or readings behind the daily figure.
What we never do with it. We do not use Apple Health data, or anything derived from it, for advertising or marketing. We do not sell it. We do not share it with data brokers, or with any third party for their own purposes. It is used only to complete the habits you asked it to complete.
Children. A child profile cannot connect Apple Health. Child habits are logged by hand.
Turning it off. You can revoke access at any time in iOS Settings → Privacy & Security → Health → TellySynco, or by choosing Disconnect inside TellySynco. Disconnecting stops all reading and all writing back. Habit days you already logged stay in your history, and anything TellySynco already saved into Apple Health stays in Apple Health — those are your records, and removing them is yours to do from the Health app. Health-derived habit entries already stored with us are deleted when your account data is deleted, as described in Section 7.
6. Children's Privacy
TellySynco is designed for family use. Child accounts are managed by the household administrator (parent/guardian). We comply with applicable children's privacy regulations and do not knowingly collect data from children under 13 without parental consent.
7. How Long We Keep Your Data, and How to Delete It
While your account is active. We keep your household's information for as long as the account exists, because the service is built on that history — past events, completed tasks, and habit streaks are only meaningful if they are still there. We do not keep it after the account is deleted, except as set out below.
Getting a copy. You can download everything we hold about your household as a JSON file at any time, from Settings → Privacy & Security → Export My Data. The export covers your household profile, adult and child member profiles, tasks, calendar events, connected calendar accounts, and registered devices.
Deleting it. The household owner can delete the account from Settings → Privacy & Security → Delete My Account. Doing so immediately takes the household and every profile in it out of service, and schedules permanent deletion for 30 days later. Within those 30 days the owner can cancel from the app and everything is restored; once the 30 days elapse, the data is erased and cannot be recovered.
Erasure removes the household record and all adult and child profiles; calendar events, event privacy settings, and connected calendar accounts; tasks and their reminders; habits and every habit completion, including any derived from Apple Health; shopping lists, meal plans, and recipes; allowances, budgets, and transactions; streaks and achievements; status updates; saved media and events parsed from photos; smart-home device links; records of your use of the Synco assistant; registered devices; and outstanding household invitations. Your sign-in accounts with our authentication provider are deleted at the same time.
If you are not the household owner. Email us at saad@thefamsync.com and we will delete your personal data. A parent or guardian can remove a child's account at any time from the household screen, which deletes that child's profile.
Limited exceptions. Encrypted operational backups may retain a copy for a short period after deletion before they are cycled out. We may also keep records for longer where the law requires it — for example billing and tax records — or where we need them to resolve a dispute or enforce our Terms. Anything kept for those reasons is kept only for as long as that reason lasts.
8. Your Rights
You can access, update, or delete your personal data at any time through the Settings page in your TellySynco account. Section 7 explains how to export your data and how deletion works. You may also request a copy or a deletion by contacting us at the address below.
