Privacy Policy
Last updated: November 10, 2026
This policy explains how TallyNorth (“we”, “us”), a sole proprietorship based in Canada, handles information in TallyNorth Calendar Sync (the “Add-on”), a Google Sheets add-on, and on tallynorth.app.
Summary
- The Add-on runs inside your own Google account. Your spreadsheet data and calendar events are processed there and are not sent to or stored on our servers.
- We do not sell, rent or share your data, and we do not use it for advertising or to train AI models.
- The only information that leaves your Google account is your license key (if you buy Pro), sent to our payment provider to check that it is valid.
Google user data the Add-on accesses
| Permission | What it is used for |
|---|---|
View and manage the spreadsheet the Add-on is installed in (spreadsheets.currentonly) | Read the rows you choose to sync; add one “Calendar Event ID” column; create a new tab when you export calendar events. No other spreadsheets are accessed. |
See, edit, create and delete calendars you can access (calendar) | List your calendars so you can pick one; create, update or (only if you enable it) remove the events that come from your sheet; read events in the date range you choose when exporting to a sheet. |
Display content in a sidebar (script.container.ui) | Show the Add-on’s sidebar. |
Run when you are not present (script.scriptapp) | Only if you turn on hourly auto-sync (Pro): a time-based trigger re-runs the sync with your saved settings. |
Connect to an external service (script.external_request) | Only to validate a Pro license key with Polar (see below). |
What is stored, and where
- In your spreadsheet: your column choices and options, and the list of event IDs the Add-on created (document properties), plus the visible “Calendar Event ID” column.
- In your calendar: each event the Add-on creates carries a small private tag (a fingerprint of its row) so re-running can detect changes.
- In your Google user properties: your license key and the date it was last validated.
- Removing the Add-on or deleting the column/tab removes this data from our control; we never had a copy.
Payments and license validation
Pro is sold through Polar Software Inc. (polar.sh), which acts as merchant of record and processes your payment, billing details and tax. Their privacy policy applies to that information. When you activate a key, the Add-on sends the key and our organization ID to Polar’s license validation service and receives back whether it is active. No spreadsheet or calendar data is included.
Google API Services User Data Policy
TallyNorth Calendar Sync’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We do not transfer Google user data to third parties, use it for advertising, or allow humans to read it, except with your explicit consent for support, for security purposes, or to comply with law.
Website
tallynorth.app is a static website hosted on Cloudflare. It does not use advertising or tracking cookies. Cloudflare may process standard request logs (such as IP address) for security and delivery.
Your choices
You can revoke the Add-on’s access at any time at myaccount.google.com/permissions, remove auto-sync from the sidebar, and delete the “Calendar Event ID” column. To ask a question or request deletion of any support emails we hold, contact us.
