864zeros LLC ("864zeros", "we", "us") builds local-first, privacy-first Google Workspace™ Add-ons, browser extensions, and software tools. Contact: [email protected].
864zeros products are local-first. Our browser extensions store the content you create or capture — for example your saved tabs, links, notes, and settings — locally on your device using the browser's own storage (chrome.storage.local / IndexedDB). Our Google Workspace™ Add-ons (including ChoiceGuard and all 864 Foundry add-ons for Google Forms™, Sheets™, Docs™, Slides™, Gmail™, and Drive™) execute inside Google Apps Script™ and store configuration state inside your own Google account using native PropertiesService (DocumentProperties and UserProperties). By default, this data:
When you activate a paid lifetime license key in a Google Workspace™ Add-on (such as ChoiceGuard Pro), the add-on sends a single verification request to https://api.864zeros.com/v1/license/verify containing only your license key string, product slug, and a randomly generated anonymous installation UUID to enforce seat limits. Zero Google Forms™ responses, document contents, respondent lists, or personal Google profile data are ever transmitted to or stored on 864zeros servers.
864zeros's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. The use of raw or derived user data received from Workspace APIs will adhere to the Google User Data Policy, including the Limited Use requirements.
https://www.googleapis.com/auth/forms.currentonly in ChoiceGuard to read Multiple Choice, Dropdown, and Checkbox options, tally submission counts, and update available options when capacity limits are reached, plus standard Google Workspace Marketplace™ sign-in identity scopes userinfo.email and userinfo.profile handled by Google's authentication session). Our add-ons do not collect, extract, or warehouse aggregated or anonymized Google Workspace™ user data on external servers.onFormSubmit triggers, or restoring original question choices). Raw and aggregated/anonymized Google user data is never used for targeted advertising, personalized ads, creditworthiness/lending determinations, data brokering, or any purpose unrelated to providing or improving the add-on's user-facing functionality.POST request to https://api.864zeros.com/v1/license/verify containing only the license key string, product slug, and a randomly generated anonymous installation UUID—never Google user data or form/document contents.PropertiesService (DocumentProperties and UserProperties), protected at rest and in transit by Google Cloud encryption and strict per-document/per-user OAuth 2.0 least-privilege isolation (*.currentonly / drive.file) and concurrency mutex locks (LockService). All license key verification calls to api.864zeros.com are encrypted in transit over HTTPS / TLS 1.3+, authenticated via HMAC-verified entitlements, and strictly isolated from any Google Workspace™ content.PropertiesService persists only while you use the add-on and is immediately deleted when you click "Deactivate / Restore" in the add-on sidebar, uninstall the add-on from Google Workspace™, or delete the underlying Google file. To request immediate deletion of an anonymous license-seat UUID record associated with a Pro license key, email [email protected] and we will purge the activation record within 7 business days.Inside our installed software products (Google Workspace™ Add-ons, browser extensions, and desktop/mobile applications), our local-first boundary is strict:
Our Google Workspace™ Add-ons and browser extensions request only the minimum narrow permissions needed to function:
forms.currentonly / spreadsheets.currentonly / documents.currentonly / presentations.currentonly — read and update only the active Google Workspace™ file where you launch the add-on.script.container.ui — display the add-on's configuration sidebar inside the Google Workspace™ editor.script.scriptapp — register installable triggers (such as onFormSubmit in ChoiceGuard) to process capacity limits automatically upon form submission.script.external_request — perform one-time license key verification against api.864zeros.com (or user-initiated BYOK calls where applicable).storage, tabs, sidePanel, scripting (Browser Extensions) — store data locally in your browser and act only on the tabs you explicitly select.Each product's Google Workspace Marketplace™ or Chrome/Edge Web Store listing states its exact permissions.
Some products can use AI. Where they do, they follow a Bring-Your-Own-Key model: your API key is stored locally and calls go directly from your browser or session to the provider you chose. We do not proxy, log, or receive those requests. Content sent to a provider is subject to that provider's privacy policy.
If you buy a paid product or license, payment is handled by third-party processors (such as ExtensionPay, Stripe, or official web stores). We access processor records strictly to verify license entitlement and provide reliable customer support (such as license recovery, seat resets, or refunds). We never ingest payment contact details into an internal behavioral data warehouse.
While our installed software products operate with zero in-app telemetry, we actively measure and optimize our public web properties (including 864zeros.com), store listings, YouTube and social media channels, and marketing campaigns:
Our products are not directed to children under 13 and we do not knowingly collect data from them.
We may update this policy; the "Effective" date above reflects the latest version. Material changes will be noted here.
