Privacy Policy (Subly)

Last updated: 2026-01-18

Summary

Subly is a Chrome extension that helps you manage subscription reminders in a Side Panel while using Google Calendar.

Subly stores your subscriptions locally on your device. If you enable Google integrations, Subly uses Google OAuth to:

• Create, update, and delete calendar events in your Google Calendar.
• Save and load a backup JSON file in your Google Drive appDataFolder (a hidden, app-specific folder).

Data Subly Stores

Locally (on your device)

Subly stores an app state object that includes:

• Your subscriptions (name, price, currency, period, start date, optional category)
• Optional Google Calendar linkage metadata for each subscription (calendarId, eventId, sync timestamps, last error)
• App settings (language, currency display, calendar sync preferences, Drive backup metadata, etc.)

This is stored using chrome.storage.local when running as an extension.

In Google Drive (optional)

If you use the Drive backup feature, Subly saves a JSON file (default name: subly-state.json) to your Drive appDataFolder.

• This file is not visible in your main Drive folders.
• Subly only reads/writes this app-specific file.

In Google Calendar (optional)

If you use Calendar sync, Subly creates/updates/deletes recurring all-day events that represent your subscription renewals. Those events may include:

• Event title (subscription name + "Renewal")
• Event description (amount, currency, billing period, and optionally category)

Depending on your settings, Subly may create a dedicated calendar (e.g., "Subly Subscriptions") or use your primary calendar.

Data Sharing

Subly does not sell your data and does not send your subscriptions to any third-party servers owned by the developer.

Subly may call third-party exchange rate APIs to fetch currency conversion rates. Those requests contain the selected base currency (e.g., USD) and no personally identifying information. Providers used include:

• open.er-api.com
• api.exchangerate.host

Permissions

• storage: to save your subscriptions and settings locally
• sidePanel: to render the UI in the Chrome Side Panel
• identity: to perform Google OAuth when you enable Google integrations

Host permissions include access to Google Calendar, Google Drive API endpoints and exchange rate providers.

Your Choices

• Disable the floating Google Calendar button in Settings.
• Clear local data in Settings.
• Choose whether to use Google Drive backup and Google Calendar sync.
