This policy explains which personal data Local Studio and its licence service process, why, and what your rights are.
Controller: ZeroG Labs — contact: support@zeroglabs.it (or our website https://zeroglabs.it).
1. What stays on your computer
Local Studio runs on your computer. Your pictures, videos, descriptions, prompts, characters, settings and the AI models never leave your computer and we never receive them. The app has no analytics, no tracking and no advertising.
2. What we process, and why
| Data | When | Why (legal basis) | How long |
|---|---|---|---|
| The e-mail of your purchase | at activation | to give and check your licence (contract, art. 6.1.b GDPR) | as long as the licence exists, then up to 10 years for tax and legal duties if required |
| A machine code: a one-way hash of identifiers of your Windows installation and PC (nothing readable about you or your files) | at activation and renewal | to bind the licence to your computers and prevent sharing (contract; legitimate interest in preventing abuse, art. 6.1.f) | as long as the licence exists |
| Your IP address, the app version and the time of each activation, renewal and update check | at activation, renewal (about every 7 days) and update checks | security, abuse prevention, support (legitimate interest) | up to 12 months |
| Your itch.io download key (only a one-way HMAC of it is stored) | at activation, if you bought on itch.io | to check the purchase with itch.io (contract) | as long as the licence exists |
| What you write to us | when you contact support | to answer you (contract / legitimate interest) | as long as needed for the request |
We do not sell your data and we do not use it for marketing.
3. Who else receives data
- itch.io (itch corp, USA): the store where you buy. It processes your payment and account under its own privacy policy. At activation our server asks itch.io whether your download key corresponds to a purchase of Local Studio.
- Hetzner Online GmbH (Germany, EU): hosts our licence server (data processor).
- Aruba S.p.A. (Italy, EU): our domain name and DNS.
- When you choose to download models or browse Civitai, your computer connects directly to Hugging Face, GitHub, Civitai and the other sources of the models: they see your IP address under their own policies. Local Studio does not send them anything else about you.
- If you use Local Studio from your phone with Tailscale, the connection is between your own devices through your own Tailscale account.
Transfers outside the EU (itch.io, USA) rely on the safeguards provided by those companies (such as the EU Standard Contractual Clauses or the EU-US Data Privacy Framework).
4. Security
The licence server accepts only encrypted connections (HTTPS), stores serial numbers and keys only as one-way hashes, and is reachable only through the licence service. Access to the server is limited to its administrator with a cryptographic key.
5. Your rights
You can ask to access, correct or delete your data, to restrict or object to its processing and to receive it in a portable format, by contacting us through support@zeroglabs.it (or our website https://zeroglabs.it). Deleting the licence data ends the licence (the software can no longer be activated with it). You can also complain to your data protection authority — in Italy the Garante per la protezione dei dati personali (https://www.garanteprivacy.it).
6. Age
The adult-content features of Local Studio are only for people aged 18 or over. We do not knowingly process data of minors.
7. Changes
We will publish any change to this policy here, with its date.
