Version 1.2 · effective from 11 October 2026
Translation for information; the Czech version is binding. The legally binding text is the Czech version.
In brief
Filamo does not use any analytics, advertising or tracking cookies. It stores in your browser only what is necessary for signing in and for the features you yourself use to work, and for protecting the service against bots (reCAPTCHA). That is why we do not display a consent banner: no consent is required for such storage (§ 89(3), second sentence, of Act No. 127/2005 Coll., on Electronic Communications – the exemption for storage strictly necessary to provide a service explicitly requested by the user; Article 5(3) of Directive 2002/58/EC).
What we store on the filamo.cz domain
| Name | Type | Stored by | Purpose | Duration |
|---|---|---|---|---|
| firebaseLocalStorageDb (and related keys beginning with “firebase:”) | IndexedDB / localStorage | Firebase Authentication (Google) | keeping you signed in – without it you would have to sign in every time you open the page | until you sign out |
| keys beginning with “firebase:” when signing in with a provider (Google, Microsoft, Facebook, Apple) | sessionStorage | Firebase Authentication | completing sign-in in the pop-up window | until the tab is closed |
| filamo.nastaveni.v1 | localStorage | Filamo | your print, price and printer settings (so that you do not have to enter them again) | until you delete them |
| filamo.tryska.v1 | localStorage | Filamo | the selected nozzle diameter for the printability check | until you delete it |
| filamo.nabidky.v1 | localStorage | Filamo | default pricing, terms and validity period of your quotations for your customers (Premium plan) | until you delete them |
| filamo.jazyk | localStorage | Filamo | the selected language of the pages (“cs” or “en”) from the CZ/EN switch, so that the pages are displayed in the same language next time; it is not sent to the server | until you change or delete it |
| filamo.jazyk.nabidnuto | localStorage | Filamo | a flag indicating that Filamo has already redirected you once on your first visit according to your browser language (so that it does not happen again); it is not sent to the server | until you delete it |
| filamo-pozvanka | localStorage | Filamo | the code from a personal “Invite a friend” link, so that after a new account is registered the invitation is assigned to the person who sent the link | no longer than 30 days; deleted after sign-in |
| firestore/… (data cache) | IndexedDB | Firebase (Google) for Filamo | a copy of your application data (projects, stock, account) on the device, so that it does not have to be downloaded again | until you sign out or clear the browser data |
| firebase-app-check-database (and _grecaptcha) | IndexedDB / localStorage | Firebase App Check and reCAPTCHA (Google) | a token proving that requests to the database, storage and sign-in come from the genuine Filamo application, and reCAPTCHA data for issuing it (below) | the token until it expires (usually 1 hour), then it is renewed; reCAPTCHA data as determined by Google |
| filamo.ucet.… | sessionStorage | Filamo | a flag indicating that the account has already been verified with the server in this session (saves requests) | until the tab is closed |
| filamo.pwa.iosNavod | localStorage | Filamo | a flag indicating that you closed the “Add to Home Screen” instructions on your iPhone or iPad (so that they are not shown again); it is not sent to the server | until you delete it |
| filamo.oznameniVop | localStorage | Filamo | the version number of the terms and conditions for which you closed the bar announcing the change (so that it is not shown again); it is not sent to the server | until you delete it |
| filamo-shell-…, filamo-statika-…, filamo-stranky-… (service worker) | Cache Storage | Filamo | copies of the pages, scripts, styles and icons of the application, so that Filamo loads faster and shows a “You are offline” page without a connection; no account data, server (API) responses or sign-in data are stored | until the next version of the application (older copies are deleted automatically) or until you clear the browser data |
Filamo itself does not set any HTTP cookies.
Bot protection – reCAPTCHA Enterprise (Google)
Filamo protects sign-in, the database and storage with Firebase App Check with reCAPTCHA Enterprise from Google. It runs invisibly (without challenges such as “select the images”) on pages where sign-in is loaded. A script from www.google.com assesses data about the device, the browser and interaction with the page, and Filamo receives only a token confirming that the request does not come from a bot. In doing so, reCAPTCHA stores its own cookie on the google.com domain (e.g. _GRECAPTCHA, valid for up to 6 months) and, on the filamo.cz domain, the data listed in the table above. Details: Privacy Policy and Google’s policies.
Why without consent: the protection is necessary so that the service you request (sign-in, saving projects, payments) can work securely – without it, the genuine application cannot be distinguished from forged requests, and once the protection is enforced the server rejects requests without a token. It is used only for security, not for analytics or advertising (§ 89(3) of Act No. 127/2005 Coll., Article 5(3) of Directive 2002/58/EC).
Third-party services that you open yourself
- Sign-in with Google, Microsoft, Facebook or Apple – the sign-in window runs on the provider’s domain, and the provider uses its own cookies in accordance with its policies (e.g. Google: https://policies.google.com/technologies/cookies).
- Payment (Stripe Checkout) and the billing portal – these run on the stripe.com domain; Stripe uses cookies necessary for payment and fraud prevention in accordance with its policies (https://stripe.com/cookie-settings).
You open these pages yourself when you sign in or pay; Filamo does not control their cookies.
How to delete the storage
Delete the data of the filamo.cz website in your browser settings (Safari: Settings → Safari → Advanced → Website Data). Signing out deletes the sign-in data and the data cache (IndexedDB). Your print, nozzle and quotation settings are thereby reset to their default values. Deleting your account deletes, in the browser in which you delete the account, all Filamo items (filamo.…, filamo-pozvanka) as well as the data cache; on other devices you can delete them by signing out or by deleting the website data.
The application loads files from your projects (sketches, previews) into temporary addresses in the browser’s memory (blob:), which cease to exist when the page is closed – no permanent public links are created.
Changes
Should we wish in future to use a tool that is not strictly necessary (for example analytics or marketing tools), we will ask for your consent in advance – with the option to refuse it just as easily and to change it at any time – and we will activate the tool only after you have given your consent. We will always update this document and the privacy policy in advance.
This is the current version (1.2, effective from 11 October 2026). Each further version will be published here with a new version number and effective date. On request we will send you the version you agreed to – write to support@filamo.cz.
