This Cookie Policy explains how Blendlens s.r.o. ("Blendlens", "we", "us" or "our") uses cookies, local storage, and similar technologies on the marketing website blendspace.io, the Blendspace web application at app.blendspace.io, the Blendspace mobile apps, our e-commerce plugins, and related services (together, the "Service"). It should be read together with our Privacy Policy.
This Cookie Policy is issued in compliance with Directive 2002/58/EC (the "ePrivacy Directive"), Czech Act No. 127/2005 Coll. on Electronic Communications (§ 89), the GDPR, the UK PECR, and equivalent laws in other jurisdictions where we operate.
Cookies are small text files placed on your device by websites you visit. They are widely used to make websites work, improve user experience, and provide analytics and marketing.
Local storage and session storage (part of the Web Storage API) allow websites and web applications to store information on your device in a similar way to cookies, but they are not automatically sent to the server with each request. Local storage is used by modern single-page applications such as our web app.
Under EU and UK law, the rules that apply to cookies (consent, information duty) apply equally to any technology that stores information on your device — including local storage, session storage, web beacons, pixel tags, and device fingerprinting.
We classify these technologies into four categories:
Blendspace has a minimal-tracking architecture:
Authorization header from the web application, and by a
per-device key sent in the x-api-key header from the mobile apps.The Blendspace web application stores the following items in your browser's local storage. These items are domain-scoped to app.blendspace.io, are not transmitted to our server automatically with every request, and are cleared when you log out or when you clear your browser storage.
| Name | Purpose | Category | Lifetime |
|---|---|---|---|
blendspace_token |
JSON Web Token used to authenticate you against our API | Strictly necessary | Until you log out |
blendspace_user |
Cached profile information (name, email, language, unit preference, avatar URL) to avoid unnecessary API calls | Strictly necessary | Until you log out |
blendspace_active |
Identifier of your currently active Blendspace workspace | Functional | Until you switch workspace or log out |
blendspace_guide_completed_<userId> |
Flag indicating that you have completed the onboarding tour, so we do not show it again | Functional | Persistent (until you clear browser storage) |
All of the above items are used for the Service to function and to remember your preferences. They are not used for analytics or marketing. Because the web application does not work without authentication, strictly necessary items are set without asking for consent, in line with § 89 of the Czech Electronic Communications Act and the ePrivacy Directive.
None. Our marketing website sets no cookies and stores nothing on your device. It loads no analytics, no advertising and no tag-management service.
Because nothing beyond what is strictly necessary is stored or read, there is nothing to consent to and no consent banner is shown. See Section 7.1.
When you use certain features of the Service, your browser is directed to third-party services. Those services set cookies on their own domains, not on blendspace.io or app.blendspace.io. We do not control these cookies. They are governed by the respective providers' privacy policies.
These third-party cookies are set only when you actively interact with the respective service (for example when you click "Sign in with Google" or proceed to Stripe Checkout). They do not load in the background.
When an online store or other third-party website embeds a Blendspace 3D preview or AR viewer, that embed does not set any cookies or persistent storage on behalf of Blendspace. The embed loads a 3D model and sends anonymous event notifications (impressions, AR views, viewer interactions) to our API. The operator of the embedding website is responsible for its own cookie consent banner and privacy notice. See Sections 2 and 13 of our Privacy Policy for details.
Our marketing website sets no cookies and stores nothing on your device beyond what is strictly necessary, so there is nothing for you to consent to and no banner is shown. If we ever introduce analytics or any other non-essential storage, we will ask for your consent before anything is set, and this Policy will be updated first.
Most browsers allow you to control cookies and storage through their settings. You can:
Blocking strictly necessary local storage in our web application will prevent you from staying signed in and will therefore break the Service.
Resources for managing browser storage: Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge.
If you are visiting from the United Kingdom, Switzerland, Brazil, Canada, Australia, or another jurisdiction with cookie laws, the principles described in this Cookie Policy apply to you as well. In particular:
We may update this Cookie Policy from time to time to reflect changes in technology, legal requirements, or our Service. The updated policy will be posted at blendspace.io/cookies.html with a revised "Last updated" date. Where required by law, we will ask for your renewed consent.
