Terms of use

By installing or running Lytra you accept these terms.

  1. 1What Lytra is

    Lytra is a free, fan-made companion for MARVEL SNAP. It shows an overlay with your deck and what your opponent has played. To do that it reads, on this computer only: the game's log and the state files the game writes to disk, and the game's memory while the game runs.

    It only reads. It does not inject anything into the game, change it, automate it or hide from it. And it shows only what the game already shows you: never your opponent's hand, deck or draws.

  2. 2Nothing about you leaves your computer unless you choose it

    Lytra sends nothing about you, your account or your matches over the internet on its own. It connects to GitHub (github.com/teoisnotdead/lytra) to check for new versions of Lytra and download them. Two things go to lytra.app, and only when you choose them.

    A bug report. When you choose Send a bug report in its tray menu, and only then, it sends what the overlay showed, a read of the game's memory (your deck, your profile and the match), the game's log, which names your recent opponents, and the match the game last saved. It is kept private, read only by Lytra's author to find the bug, and deleted after 90 days.

    A public profile. It is off until you turn it on in the dashboard. Then anyone can see your Ranked and Conquest matches at stats.lytra.app, under the name you choose (stats.lytra.app/name). For each match: when it was played, the mode, your deck, its name and the variants it wore, the result and cubes, snaps and retreats, the cards drawn and played, and the locations. The links you add are shown with them. Your opponent's name and cards never go up. With Update after every match on, each new match goes up as it ends. You can hide the page or delete the profile in the dashboard at any time: deleting removes it and its matches from lytra.app at once, and frees the name.

    Everything else stays on this computer. Your match history does: the dashboard is served by Lytra to your own browser, on this computer, and nothing outside it can reach it. So do the card list and the card pictures Lytra uses, which come from your own MARVEL SNAP installation.

  3. 3Not affiliated

    Lytra is not affiliated with, endorsed or sponsored by Second Dinner, Nuverse, Marvel or Disney. MARVEL SNAP, its cards, names and art belong to their owners. The card art Lytra takes from your installation is for your screen only; do not redistribute it. Public profiles on stats.lytra.app show the game's card art from lytra.app's own copy, free and with no commercial purpose, as fan sites do. Its owners can ask for it to be taken down on Lytra's Discord (discord.gg/QNSTW2PNqF).

  4. 4At your own risk

    MARVEL SNAP's terms of service may forbid or restrict third-party tools that read the game. You alone decide whether using Lytra fits the rules of your account, and you alone bear any consequence, including action taken against your account. Nobody can promise that Second Dinner allows it.

  5. 5No warranty

    This is a test version. Lytra is provided "as is", without warranty of any kind: it may be wrong, may stop working after a game update, and may fail. To the extent the law allows, its author is not liable for any damage or loss arising from its use, including action taken against your MARVEL SNAP account.

  6. 6Changes

    A new version may change these terms; each installer shows the ones that apply to it. You can stop at any time by uninstalling Lytra.
