Privacy Policy

Lets get to the point. Here is a list of things we dont do:

★ We do NOT show ads.

★ We do NOT store or even transmit any of your data to us or a third party.

★ We do NOT yet charge for the product.

★ We do NOT store any of your data outside your device.

In fact only your local Chrome browser (or mobile app) reads, stores and uses your data, only inside your own device (computer or phone). It is never sent outside except to Trello itself or to your sync spreadsheet when using the Google spreadsheet sync modes.

We do have plans to charge soon for the "Pro" version, see here.

Plus for Trello is open-source, see the full code in GitHub or the chrome debugger.

For the mobile and power-up Plus for Trello policy see here for more details. The only difference is that those versions also send anonymous statistical usage information. 

Permissions for the Chrome extension are configured to the minimum possible so you can be sure that it only accesses the data it needs and no more, and that the data is not sent anywhere unexpected. These permissions are controlled by Chrome and restrict the extension to only access data from Trello (or Google spreadsheets when using that sync mode).

When Plus requests more permissions, Chrome will always ask you to accept or deny the permission. Plus requests additional permissions when you use one of the "Google sync" methods or enable "Pro" (to check in the future for licence payment in the Chrome store).

The initial permissions when you add the extension are:
"Read and change you data on,".

If you also enable one of the "Google sync" methods, the list will include ", ". If "Pro" is enabled, additional permissions are listed here.

Verify these permissions by finding Plus in your extensions list:
On your browser, click menu 
Select More tools > Extensions
Find "Plus for Trello" and click "Details".
See more about Chrome permissions.

How Plus uses and secures your data

Plus does not collect any data about you (not even your email) or Trello data anywhere outside your Chrome browser storage (or the legacy "Google sync" spreadsheet if you enabled it). For "Google sync", the spreadsheet is created in your Google Drive with permissions only to you as owner. Plus cannot read your spreadsheet outside of your browser extension and cannot read, write or list any other Drive file. Plus can only read and write to the sync spreadsheet you created within the Chrome extension. We use the tightest possible permission as provided by the Google Drive API scopes by using the drive.file scope (per-file access).

Plus reads from API and web pages to insert itself in the right places and sync with Chrome or the mobile app, reads API data from boards you joined, their lists and cards, and writes data to Trello as card comments (and card titles if enabled). These all happens while you have a Trello page open.

If you also enable "background sync", it will read from Trello while Chrome is open, even if you have not opened a Trello tab.

Plus uses to read public news from the Google+ page of Plus and display them in the Plus header "new!" icon to notify users whenever there are new features posted on the Google+ page. This same "scope" is also used when you enable one of the "Google Sync" methods and click the "Create Google Spreadsheet" button.

If you enable the "Pro" version, Plus will also send fully anonymous statistical data to Google Analytics (after you approve the permission to do so) so we know which are the popular features to improve.

Security of your data

All the Plus data is inside a Chrome local web sql database, chrome storage (local and sync) and localStorage.
Chrome manages web sql with a super-fast and incorruptible sqLite database (a Chrome feature).

Plus provides a "Reset Sync" button in case you ever need to rebuild all the data from scratch. Because S/E is saved inside Trello (or in a Google spreadsheet for those using "Google sync") Plus can remove all the data it saved in your device during reset, followed by a full sync. This will work even if your hard-disk fails and is replaced by a new one, or if you add Plus to a different computer.

If you are using "Chrome sign-in" (highly recommended), Plus preferences and active timers are stored in chrome "sync" storage which makes them available in your other desktop computers where you use Chrome sign-in.

If you are not signed-into Chrome you can still sync your Trello data and S/E in other devices but active running timers will not sync across devices (so start and stop them from the same computer.)

Remove your data

When you logout of Trello, Plus will still have a local, cached copy of your data and you can continue running reports, burn-downs and the Chrome Plus menu.
If you wish to remove all your data, follow these two steps from Plus help:

  1. Under "Sync", set disabled sync.
  2. Under "Utilities", click "Reset sync".
Plus removes all Plus local data in your machine and Plus "chrome sync" storage (which stores your preferences and your active running timers.)

Data saved

Plus only saves data in your Chrome browser local/sync storage, on Trello itself (as card comments), and on the sync spreadsheet for legacy or "stealth sync" users. Plus saves the following data inside your Chrome browser:
  • S/E history rows, board, list and card information.
  • Active Timers.
  • card 'draft s/e'.
  • Preferences.
Some of these settings, like active timers and preferences are saved on chrome "sync" storage, which means it is also stored in Google Chrome sync servers if you are signed into Chrome. If you wish, you can enable encryption of these data in Google servers using your own passphrase (thus Google itself of wont be able to read it, but it doesn't really matter as it only stores the card "id".)

Network usage

Plus reads from so it uses some of your network bandwidth. This usage is typically very small. During the "first sync" with Trello, Plus will use more bandwidth as it reads all your boards history. That size depends how many cards, card comments and card movements there are boards where you are a direct member.

A "first sync" with hundreds of boards and many thousands of history entries typically takes under 2 minutes to sync on a good internet connection.

After that, all further syncs are almost immediate and use almost no bandwidth. The only case when Plus could again take a little to finish sync is when you become a member of a board that has extensive existing history.

Open Source

The latest source code is always at github for your inspection. You can also inspect the code directly from the chrome debugger. Its unminimized and with full comments.

For "Google sync" users only (legacy and stealth modes)

If you select "Google sync", Chrome asks you to approve additional permissions for Google spreadsheets. Plus reads and writes to to sync with the Google spreadsheet. Chrome will ask you to approve that Google permission the first time you set it up.

Note that Plus never asks or saves your Google password. Plus uses the latest industry-standard oauth2 protocol built-in in Chrome identity. You enter your Google password in a separate Chrome page when you sign-in to Chrome.

Plus also asks additional Google permissions if you click the "create Google spreadsheet" button so it can create the spreadsheet in your Google Drive. Those permissions only give access to the single Google Drive spreadsheet file created by Plus (scope ""). The permission (an oauth2 token, not a password) is remembered by Chrome.identity (not Plus) until you revoke access.
For more details see Authorizing requests to a spreadsheet and Creating a spreadsheet in Drive.

View or revoke your approved Google spreadsheet/drive file permissions under 
"Plus for Trello" in the Google account security page

Turning on and off the extension

Manage the extension using the Google Chrome extensions help.
You can also turn off just the features that modify the trello page by using the first checkbox in the Plus help pane, "Disable changing pages." In that case, Plus continues to function and sync, just it wont show in trello pages.
