Privacy Policy — Assetli Finance for Google Sheets
Last updated: August 19, 2026
Applies to: the Assetli Finance add-on for Google Sheets, published on the Google Workspace Marketplace
This page describes the add-on, and only the add-on. The Assetli web application at assetli.app is a separate product with its own privacy policy; nothing described there applies here, because the add-on has no connection to it.
1. In short
- The add-on does not ask you to sign in and has no connection to an Assetli account.
- It reads only the numbers you enter yourself, and only in the spreadsheet it is open in.
- It sends nothing to assetli.app. It has no network permission at all.
- It stores nothing outside the cells of your own spreadsheet.
- There is no analytics, no tracking, and no third-party service involved.
Because nothing leaves your spreadsheet, we receive no data about you or your finances from the add-on, and we hold none.
2. No account, no sign-in
The add-on works entirely inside Google Sheets. It does not ask for an Assetli account, does not know whether you have one, and cannot read anything from one. It asks for no password and stores no credentials.
It cannot reach the network at all. The manifest requests no network permission (script.external_request), and the build that produces the published script rejects any version of it that so much as mentions Google's network API (UrlFetchApp) or an Assetli address. A version that tried to send something would therefore never be published in the first place.
3. What the add-on reads
Only what you give it:
- the values you pass to a formula — an amount, a rate, a term — for example
=ASSETLI_MORTGAGE_SCHEDULE(3500000, 4.89, 30); - the input cells of a calculator sheet that the add-on inserted at your request;
- the language setting of the spreadsheet and of your Google account, used for one thing only: deciding whether to answer in English or in Czech.
It does not read the rest of your spreadsheet, and it cannot open any other file in your Google Drive — the spreadsheets.currentonly permission makes every other file unreachable. It does not read your name or your e-mail address.
4. What is sent to assetli.app
Nothing. The calculators are arithmetic that runs inside your spreadsheet. There is no request, so there is nothing to list: no formula arguments, no spreadsheet content, no identifier, no version header.
5. The permissions the add-on asks for
Two, and nothing beyond them:
| Permission (OAuth scope) | Why the add-on needs it |
|---|---|
https://www.googleapis.com/auth/spreadsheets.currentonly |
To insert the calculator sheet and to read the values you entered — in the spreadsheet the add-on is open in, and in no other file. |
https://www.googleapis.com/auth/script.container.ui |
To show the add-on's menu under Extensions and the About the add-on dialog. |
Neither of them can reach the network, and neither gives access to your Drive beyond the current spreadsheet. The published script is marked @OnlyCurrentDoc, and the build fails if the manifest ever asks for a scope beyond these two.
6. What is stored, and where
| What | Where | For how long |
|---|---|---|
| the values and results you see | the cells of your own spreadsheet | as long as you keep them |
That is the whole list. The add-on writes nothing to Apps Script's PropertiesService and nothing to its CacheService — the published script contains neither. It loads no external script, font or image, and contains no analytics or tracking of any kind.
7. Links in the inserted sheets
A calculator sheet inserted by the add-on contains one ordinary hyperlink to the matching calculator on assetli.app. It behaves like any other link in a spreadsheet: nothing is sent when the sheet is created, and clicking it is a normal visit to a website. From that click on, the Assetli privacy policy applies to the website you have opened.
8. Removing everything
Uninstall the add-on in Google Sheets (Extensions → Add-ons → Manage add-ons) and it is gone. It has nothing stored anywhere else to leave behind, and there is nothing on our side to delete, because nothing ever reached us.
Calculator sheets already in your spreadsheet stay where they are. They are part of your spreadsheet and keep working as ordinary formulas until you delete them yourself.
9. Google API Services User Data Policy
Assetli Finance's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
10. Changes to this policy
This page describes what the add-on does today. If a future version ever does more than calculate inside your spreadsheet, this page is updated in the same release as the change — and any new permission has to be approved by you before that version can run at all.
