Privacy Policy
Calli — Calendar & Tasks
Published by TeaTime Studio LLC
Effective Date: August 15, 2026
TeaTime Studio LLC (“we,” “us,” or “our”) built Calli (“the App”) as a calendar and task management application. This Privacy Policy explains what personal data the App accesses, collects, uses, and shares, who it is shared with, how we secure it, and how long we keep it.
By using Calli, you agree to the collection and use of information as described in this policy.
1. Information We Collect
Account information
Calli requires an account. You sign in with Google Sign-In. We do not currently offer sign-in by email and password, or any other sign-in method.
When you sign in we receive and store:
Your email address, from your Google account.
Your name, as supplied by that account. We store the first name as your initial display name, which you can change at any time in Settings.
A user ID, generated by our authentication system to identify your account.
Your most recent sign-in time.
If your Google account includes a profile picture, its web address is part of the sign-in record retained with your authentication data. Calli does not currently display it anywhere in the App.
Sign-in tokens are exchanged with Google during sign-in to verify your identity. Your Google password is never seen by, or shared with, the App.
Calendar and task data
Calli stores the events and tasks you create, including:
Titles and descriptions
Start and end dates and times, and whether an item is all-day
Recurrence rules and end dates
Reminder settings
Task completion status
If you add a location to an event: the street address and the geographic coordinates of the place you selected
Event titles and descriptions are free text, so they may contain whatever you choose to type. Please avoid entering sensitive information you would not want stored.
App preferences
Your display name, colour theme, and preferred week start day.
Subscription information
If you subscribe to Calli Plus, we store your subscription status, the product you purchased, its expiry date, and the identifiers our subscription provider uses to recognise your purchase.
We never receive your payment method or billing details. All transactions are handled by Google Play, through our subscription management provider, RevenueCat.
Diagnostic data
When the App crashes or hits an unexpected error, a diagnostic report is sent automatically to our crash reporting provider, Sentry. Reports contain technical information: error messages, stack traces, app version, device and operating system characteristics, and a trail of recent in-app activity. If the problem involved a particular event or task, the report may also include its identifier, its start and end times, and its repeat rule — the details we need to reproduce faults in timing and repeats.
To limit what these reports can reveal about you:
Your user ID is attached, but your name and email address are not.
Event titles, descriptions, and location text are never included.
Screenshots and screen layouts are never attached.
Sentry’s automatic collection of personal information is switched off.
Values matching sensitive patterns — passwords, tokens, keys, and similar — are replaced with
[REDACTED]before a report leaves your device.
Location data
Calli requests your device location only at the moment you search for a place to attach to an event, and uses it only to rank nearby results first. That coordinate is sent to Mapbox with your search text, held in memory for the duration of the search, and never written to your device or our servers.
Granting location access is optional. If you decline, location search continues to work without the nearby-results ranking. Calli never accesses your location in the background.
2. Information We Do Not Collect
Calli does not collect or access your contacts, photos, videos, microphone, audio, messages, files, health or fitness data, web browsing history, or the list of apps installed on your device.
Calli contains no advertising, analytics, tracking, or attribution software. We do not collect or use an advertising ID or any other device or installation identifier, and we build no advertising or user profile about you.
Reminders are scheduled and delivered locally on your device. Calli does not operate a push notification service, and your reminders are not sent to any server for delivery.
3. How We Use Your Information
We use your information only to:
| Purpose | What this covers |
|---|---|
| App functionality | Store and sync your calendar and tasks across your devices, deliver reminders, search for event locations, and remember your display preferences |
| Account management | Create and maintain your account, verify your identity, secure access to your data, and manage your Calli Plus subscription |
| Analytics | Diagnose crashes and technical problems, including faults in event timing and repeats, and monitor the App’s stability |
We do not use your information for advertising, marketing, personalization, profiling, or automated decision-making.
4. Who We Share Your Information With
We use the following providers to operate the App. Each acts as our service provider — it processes data on our behalf and on our instructions, and is not permitted to use your data for its own purposes. Each receives only what its function requires.
| Provider | Function | What it receives | Its policy |
|---|---|---|---|
| Supabase | Cloud database, authentication, and sync | Account details, all calendar and task content, preferences, subscription status | supabase.com/privacy |
| RevenueCat | Subscription management | Your user ID and purchase information from Google Play | revenuecat.com/privacy |
| Sign-in, and app distribution and billing via Google Play | Standard sign-in information; purchase and billing details, which Google handles directly | policies.google.com/privacy | |
| Sentry | Crash and error reporting | Diagnostic reports as described above, including your user ID | sentry.io/privacy |
| Mapbox | Location search | Your search text, and your device coordinates if you granted location access | mapbox.com/legal/privacy |
We do not sell, rent, or trade your personal information. We do not share it with any third party for that party’s own advertising, marketing, or analytics purposes.
We may disclose information if required to do so by law, or where necessary to protect our legal rights or the safety of our users.
5. Data Storage and Security
Your data is stored both on your device and on our cloud infrastructure. The App is built to work offline: changes are saved on your device first and synced when a connection is available.
Our security measures include:
Encryption in transit — all communication with our servers and providers uses HTTPS/TLS.
Row-level security — database rules enforce that each account can read and write only its own records, applied at the database itself rather than only in the App.
Secure credential storage — your sign-in tokens are held in your device’s dedicated secure storage (the Android Keystore or iOS Keychain).
Minimised diagnostics — personal information is stripped from crash reports as described in Section 1.
Excluded from device backups — your calendar data is excluded from Android cloud backup and device-to-device transfer, so it is not copied off your device. Nothing is lost: your data re-syncs from our servers when you sign in.
Your calendar data stored on your device is protected by your device’s own security — your screen lock and the operating system’s app sandboxing and storage encryption. We recommend keeping a screen lock enabled.
No system is completely secure, but we take reasonable measures to safeguard your information.
6. Data Retention and Deletion
We keep your data for as long as your account exists.
When you delete an individual event or task, it is marked as deleted, hidden immediately across your devices, and retained briefly so the deletion can propagate to your other devices. It is then permanently erased from our servers, currently after about 15 days.
Deleting your account erases everything immediately. You can delete your account at any time from Settings → Delete account inside the App. This permanently removes your profile, sign-in identity, all events, tasks and recurring-series exceptions, task completion history, app settings, and subscription records from our servers, and clears the data held on your device. Deletion is immediate and irreversible; no copy is retained.
If you no longer have the App installed, you can request deletion at teatime.works/delete-account, or by emailing support@teatime.works from your account’s email address. We aim to complete these requests within 30 days.
Note that deleting your Calli account does not cancel an active subscription, because billing is managed by Google Play. Cancel there separately to stop future charges.
Signing out (without deleting your account) clears your events, settings, and scheduled reminders from your device, and cancels your local reminders. Your data remains on our servers and returns when you sign back in.
Crash reports are retained by Sentry according to its own retention schedule and are automatically deleted when it expires.
7. Your Rights
Depending on where you live, you may have the right to:
Access the personal data we hold about you
Correct inaccurate information — your display name is editable in Settings
Delete your account and all associated data, as described in Section 6
Obtain a copy of your data in a portable format
Withdraw consent for optional processing — you can revoke location access at any time in your device settings, with no loss of core functionality
Object to or restrict certain processing
Complain to your local data protection authority
Deletion and correction are available directly in the App. For access, portability, or any other request, email support@teatime.works and we will respond within 30 days. We will not discriminate against you for exercising any of these rights.
8. Children’s Privacy
Calli is not directed at children under 13, or under the applicable age of digital consent where you live. We do not knowingly collect personal information from children. If we learn that we have, we will delete it promptly. If you believe a child has provided us with personal information, please contact us at support@teatime.works.
9. Changes to This Policy
We may update this Privacy Policy from time to time. We will post the updated policy at this address, update the Effective Date above, and — where the change materially affects how we handle your data — notify you within the App. Your continued use of Calli after a change takes effect constitutes acceptance of the revised policy.
