Introduction
This Cookies Policy explains how VoiGu, Inc. (“VoiGu,” “we,” “our,” or “us”) uses cookies and similar technologies on our website, and equivalent SDKs and identifiers in our mobile apps. It should be read alongside our Privacy Policy.
What are cookies?
Cookies are small text files placed on your device by a website you visit. They are widely used to make websites work, or work more efficiently, and to provide information to the site owners. Similar technologies — such as web beacons, pixels, local storage, and device identifiers — perform the same kinds of functions on the web and inside mobile apps.
Cookies can be session (deleted when you close your browser) or persistent (stored until expiry or deletion), and either first-party (set by VoiGu) or third-party (set by our service providers).
Cookie categories
Strictly necessary
Required for the website to function. They enable core features like signing in, keeping you signed in, and security. These cookies cannot be disabled.
Functional
Remember your language so you don't have to set it every time. Disabling these may make parts of the site less convenient.
Analytics & performance
Help us understand how visitors use the site — which pages are popular, where errors occur, how long people stay — so we can improve. Our tools for this include Vercel Web Analytics and Vercel Speed Insights.
Advertising & marketing
Help us measure the effectiveness of our advertising and limit the number of times you see an ad. VoiGu uses these only with your consent (where required) and does not sell personal information to advertisers.
Cookies we set
Here are examples of cookies VoiGu and our processors place. Names may change as we improve the Service; this list is illustrative rather than exhaustive.
First-party
NEXT_LOCALE— remembers the language version of the site you last used. Functional. 12 months.vv_<post>— set when you open a blog post, so a view is counted once a day. 24 hours.voigu_session— keeps VoiGu staff signed in to the site's admin area. Not set for visitors.
Local and session storage
bugsnag-anonymous-id(local storage) — a random ID used with website error reports (Bugsnag).am_vid,am_sid,am_st(local storage) — visitor and session IDs for website analytics.voigu:viewed:<post>(session storage) — stops the same blog post view being counted twice in one visit.
Third-party
- Vercel Web Analytics & Speed Insights — page views and site performance.
- YouTube — when an embedded video is played, in privacy-enhanced mode.
Third-party cookies
Some third parties may set their own cookies when you interact with their content embedded on our site (e.g., a video player or social share button). VoiGu does not control these cookies. Refer to those providers' privacy policies for details.
Mobile app SDKs & identifiers
Mobile apps don't use cookies in the traditional sense, but rely on similar technologies to deliver comparable functionality:
- Local storage — for caching lessons and preferences.
- Firebase SDK — for sign-in, data sync, file storage, and analytics.
- Amplitude SDK — for product analytics and session replay.
- Bugsnag SDK — for crash reports, which can include your name and email.
- Advertising identifiers — VoiGu doesn't collect Apple IDFA or Google AAID.
You can control these in Profile → Privacy in the VoiGu app, and in your device's system-level privacy settings.
Managing your preferences
On the web, you can manage cookies and site data in your browser:
- Adjust your browser settings to block or delete cookies and site data. Most browsers offer help under “Settings → Privacy.”
- Our website analytics have no separate opt-out. You can block them with your browser's privacy or content-blocking settings.
In the mobile app, turn off product analytics and session replay (Amplitude) in Profile → Privacy → Usage analytics. Firebase Analytics still collects basic usage data when this is off. This does not affect transactional messages or learning-data syncing.
Please note that blocking strictly necessary cookies may prevent the website from working correctly.
Do Not Track & Global Privacy Control
Many browsers send a “Do Not Track” (DNT) signal or a Global Privacy Control (GPC) signal. Where applicable law requires us to honor these signals, we do. We treat a GPC signal as a request to opt out of the “sale” or “sharing” of personal information for cross-context behavioral advertising.
Changes to this policy
We may update this Cookies Policy from time to time to reflect changes in technology, regulation, or our operations. The “Last updated” date at the top of this page reflects the most recent revision. If changes are material, we'll let you know in-app or by email.
