NightSheetsDark mode for Google Sheets, Docs and Slides

NightSheets – Privacy Policy

Effective date: 16 October 2026 · Applies to the NightSheets Chrome extension (“NightSheets”, “the extension”) · This page: https://pages.automationglass.com/nightsheets/privacy.html

Summary

NightSheets does not collect, store on a server, sell or share your data. It changes how Google Docs, Sheets and Slides look on your screen, on your computer. The only network requests the extension itself makes go to ExtensionPay, to check whether you have Pro, and only after you have opened its upgrade, trial or log-in page. There is no analytics or telemetry of any kind.

What the extension does on Google Docs, Sheets and Slides

NightSheets runs only on docs.google.com documents, spreadsheets and presentations. There it adds its own stylesheet to the page to show a dark theme. It does not read, copy or change the content of your files, and it does not run on Gmail, Google Forms or any other website. Document content, page addresses (URLs) and your browsing history are never sent to the developer or to anyone else.

Every data item, and where it goes

DataWhere it is keptSent anywhere?
Your settings: dark mode on/off, the switch for each app, contrast preset, per-app presets, schedule chrome.storage.local in your browserNo
An approximate location, only if you type one (latitude/longitude rounded to one decimal) for sunset times. Left empty, it is estimated from your time zone; the extension never asks the browser for your location. chrome.storage.localNo
Cached “Pro active” flagchrome.storage.localNo
Licence data from ExtensionPay: a random licence key, install date, whether you have paid, when a trial started chrome.storage.sync (synced by Chrome through your Google account only if you use Chrome Sync) The licence key is sent to extensionpay.com to check your Pro status, only after you have opened the upgrade, trial or log-in page
Email address (and card details) you enter on ExtensionPay's payment, trial or log-in page ExtensionPay and Stripe, not the extensionEntered by you directly on extensionpay.com / Stripe

Removing the extension deletes the data it stored in your browser. When you remove it, Chrome opens a short thank-you page (https://pages.automationglass.com/nightsheets/uninstalled.html); no information about you is added to that address and the page has no tracking.

Payments (ExtensionPay and Stripe)

NightSheets Pro is sold through ExtensionPay, which uses Stripe to process payments.

See the privacy policies of ExtensionPay and Stripe for how they handle your data.

What NightSheets does not do

Children

NightSheets is not directed at children and does not knowingly collect any information from them.

If NightSheets is discontinued

If the extension is removed from the Chrome Web Store, copies already installed keep working with the free features, which need no network. Refunds for Pro remain available on request (see the refund policy).

Changes

If this policy changes, the new version will be posted at this address with a new effective date. Changes that affect how data is handled will also be mentioned in the extension's release notes.
