01What are cookies?
Cookies are tiny text files that websites store on your device to remember information between visits. Local storage and session storage do something similar but stay only on your device.
"Cookies" are small text files placed on your device when you visit a website. They are widely used to make websites work, to make them more efficient, and to provide information to the site owner.
"Similar technologies" include browser local storage and session storage, which store data in your browser without sending it to the server, and web beacons or tracking pixels, which are tiny graphics used to record certain interactions.
Cookies can be:
- First-party (set by the site you're visiting) or third-party (set by another domain, like an analytics provider)
- Session cookies (deleted when you close your browser) or persistent cookies (stay until they expire or you clear them)
02What we use and why
We use cookies and similar technologies for the following purposes:
Strictly necessary
These are required for the Services to function. They keep you logged in, remember your preferences, save your in-progress invoices on your device, and protect against abuse. The Services will not work properly without them. We rely on a legitimate-interest legal basis for these, and they are not subject to consent.
Analytics and performance
We use Microsoft Clarity to understand how visitors use the Services — which pages are popular, where people get stuck, and what we can improve. Clarity records anonymized session data (clicks, scrolls, mouse movement, page views) and produces aggregate heatmaps. Personal information entered into form fields is masked by default.
What we do NOT use
- No advertising cookies
- No marketing or remarketing trackers
- No social-media pixels (Meta/Facebook, X/Twitter, TikTok, etc.)
- No third-party ad networks (Google Ads, etc.)
- No data selling or sharing for cross-context behavioral advertising
03Cookies and storage in use
The specific cookies and storage entries used by the Services are listed below. This list may change as the Services evolve; we will update this page when it does.
First-party local storage
| Name / Key | Purpose | Duration |
|---|---|---|
invgen:invoices |
Saves your in-progress and completed invoices on your device so they're there when you come back | Persistent (until cleared) |
invgen:kit |
Saves your kit catalog and gear list locally | Persistent (until cleared) |
invgen:settings |
Stores your app settings, default rates, and preferences | Persistent (until cleared) |
invgen:profile |

invgen:clients |
Stores your saved client/customer list | Persistent (until cleared) |
invgen:auth |
Keeps you signed in to your account between visits (paid users) | Up to 30 days |
All invgen:* entries live in your browser's local storage on your own device. If you create an account and sign in, this data is also synced to your account on our servers — available on any device you sign into, accessible only to you — whether or not you're on a paid plan.

Payment-related cookies (Stripe)
If you visit a checkout page, our payment processor Stripe sets its own cookies to detect and prevent fraud. Stripe's cookie use is described at stripe.com/cookie-settings.
04Third-party cookies
Some cookies are set by third-party services we use to run the Services. These third parties have their own privacy and cookie policies, which govern their use of the data they collect:
- Microsoft Clarity — analytics, session replays, heatmaps. Privacy statement
- Stripe — payment processing and fraud prevention. Privacy policy
- Vercel — hosting and content delivery (no marketing cookies). Privacy policy
- Formspree — form submissions, if you use a contact form. Privacy policy
We do not control these third parties' cookies. If you want to opt out of their data collection, follow the links above.
05Your choices and controls
Browser settings
Most browsers let you view, manage, delete, and block cookies. To change your settings, see the help docs for your browser:
Note: blocking strictly necessary cookies and local storage will break parts of the app, including saving your invoices and staying signed in.
Clearing local storage
You can clear all invgen:* data from your browser at any time using your browser's "Clear site data" tool (usually under developer tools or privacy settings). Doing so will erase any invoices, kit lists, or settings stored only on your device. If you have a paid account with cloud sync, your synced data will still be available next time you sign in.
Opt out of Clarity
You can learn how Microsoft Clarity uses cookies (and how to opt out) in Microsoft Clarity's cookie documentation or by using a browser-level "Do Not Track" or "Global Privacy Control" signal (see below).
06Do Not Track and Global Privacy Control
Do Not Track (DNT): there is currently no industry-standard way to interpret DNT signals consistently, so we do not respond to them.
Global Privacy Control (GPC): we honor browser-based GPC signals where applicable. When we detect a GPC signal from your browser, we treat it as a request to opt out of any "sale" or "sharing" of personal information for cross-context behavioral advertising under U.S. state privacy laws. Note: we do not sell or share personal information for advertising in the first place, so this is a defensive setting.
07Updates to this policy
We may update this Cookie Policy from time to time to reflect changes in our practices, the technologies we use, or for legal reasons. The "Last updated" date at the top reflects the most recent version. For material changes, we'll post a notice on the Services or email you.
