Help

The most common questions about how the platform works. Click a question to read the answer.

Where do I start?

From the home page you create a new skin or open your garage to pick up a saved one. If you had one open recently, there is a shortcut back to it.

Where do saved skins go?

To the garage, each with a real preview of the car. From every card you can open it in the editor, rename it, export the game-ready zip, duplicate it or delete it, without going through the editor.

How do I colour the body?

With the Livery tool. Colour for the base tint, Texture to add patterns or images, Material to set how matte or glossy the paint is and how metallic it looks.

What about the wheels?

They have their own tool, with colour, texture and material independent from the body.

What about all the black parts around the body?

Those are the details: suspension, wheel arches, side air intakes, front wing, rear diffuser and the central strip under the car. They have their own tool, with their own colour and texture. Leave them alone and they stay the usual dark grey.

How do decals work?

You apply one from the catalogue and then place it: move it back and forth, up and down, resize, rotate and mirror it. You can paint it any colour or keep the original ones. The lock button stops the car from spinning while you work.

Why does my car already have lights on?

Every skin starts with this car model's standard lighting — numbers, rear wing, headlights — because that is what the game shows anyway. The Lights tool changes their colour and intensity. Importing a skin with its own lights replaces the defaults.

How do I get the skin into the game?

With the Export tool: it builds the zip in the format Trackmania expects. Download it and load it as a custom skin following the game instructions. The same zip can be loaded back here to resume a skin.

Do I need to sign in?

No. Without signing in the editor works fully, but skins stay in this computer's browser. Signing in with your Trackmania account copies them to the cloud too, so you find them from any machine.

Can I see other people's skins?

Yes, in the Community section: every public skin, which you can rate and copy into your garage to use or edit. Yours stay private until you publish them, from the toggle on the garage card.

Privacy policy

Last updated: 29 September 2026

This page explains which personal data TM Garage processes, why, for how long and how you can exercise your rights (EU Regulation 2016/679, "GDPR").

Who is the controller

The data controller is Davide Longo (Jaskull), who runs TM Garage. For any question about your data write to jaskulltv@gmail.com.

What the site does

TM Garage is a web editor for making Trackmania 2020 skins without graphics software. You can use it without an account; signing in with your Trackmania account is needed to save skins online, publish them to the community, generate textures with AI and buy AI credits. It is not affiliated with Nadeo or Ubisoft.

What data I process and why

  • Trackmania account: when you sign in I only receive your account identifier and nickname from Nadeo/Ubisoft. They identify you and link your skins, credits and purchases (performing the service you ask for).
  • Skins and images: the skins you save online and the images you upload or generate. They stay private until you publish them; published skins are visible to everyone together with your nickname. Of the stickers made with the AI the last 10 are kept: older ones are deleted automatically.
  • Credits and purchases: your credit balance, and for each purchase the order identifier, the pack and the account. Payment and billing data is collected by Stripe: I never see your card number (performing the contract and legal obligations).
  • IP address: to limit abuse of AI generation I keep, per day, your IP address and the number of requests. I delete it after 30 days (legitimate interest in protecting the service from abuse and its costs).
  • Reports: if you use the Bug/Feedback button I keep the text you write, the page you were on, the language and browser type, and your nickname if you are signed in or type one (legitimate interest in replying and improving the site).
  • Invites: if you arrive from an invite link I remember the code so the inviter gets their credits.
  • Statistics: I only count how many pages are opened per day, without IP or identifiers, and I use Vercel statistics (Analytics and Speed Insights), which use no cookies and do not identify people.

Cookies and data in your browser

TM Garage only uses technical cookies that are needed for it to work, so it shows no consent banner. I use no profiling cookies and no advertising.

  • tmg_session: keeps you signed in after login, lasts 30 days.
  • tmg_oauth_state: only used during sign-in to protect it, lasts 10 minutes.
  • tmg_referral: if you arrive from an invite link it remembers the code for 90 days, then it is deleted.
  • Browser storage (IndexedDB and localStorage): your skin drafts, the images you import and a few preferences (environment, columns, latest news seen) stay on your device and are not sent to me.
  • Buy Me a Coffee: the external site’s button only loads its script if you click it; the links to Buy Me a Coffee and PayPal take you to their sites, which have their own rules.

AI generation

When you generate a skin with AI the text you write is sent to Google (Gemini API) together with guide images from the site, and the result is saved in your skins. Do not put personal data in the text. Google processes that data under the terms of its APIs.

Payments

AI credits are bought through Stripe. With Managed Payments Stripe is the seller and handles payment, taxes, invoices and support for the order; for the data it collects at that stage it is an independent controller and its privacy notice applies. I only receive the outcome, the order identifier, the account and the pack.

Who I share data with

Some of these providers may process data outside the European Economic Area: in that case with the safeguards required by the GDPR (for example standard contractual clauses). Data is not sold.

  • Vercel: hosts the site, uploaded files and statistics.
  • Neon: hosts the database.
  • Google: generates images with AI.
  • Stripe: collects payments.
  • Nadeo/Ubisoft: handle sign-in with your Trackmania account.

How long I keep it

  • Account, skins and credits: until you ask for them to be deleted.
  • IP addresses for the AI limit: 30 days.
  • Reports: as long as they are needed to handle them; if you delete your account your name is removed.
  • Accounting data for purchases: kept by Stripe for the time required by law.

Your rights

You can ask to access, correct or delete your data (including your whole account with its skins), receive it in a readable format, restrict or object to its processing. Write to jaskulltv@gmail.com: I reply within 30 days. If you believe your rights are not respected you can contact the Italian data protection authority (garanteprivacy.it).

Minors

The site is not meant for people under 14: in that case a parent’s consent is needed.

Changes

If the site changes how it processes data I update this page and the date above.
