Analytics details: The maker says Google Analytics 4 does not store IP addresses and data is kept for 14 months; typed coordinates, world names, notes, and other written text are not collected.
Bedrock limitations: The maker cautions that Bedrock structure predictions can be inaccurate, the spawn is estimated, and the End's outer islands may differ.
Browser processing: World generation and searches run in the user's browser using cubiomes compiled to WebAssembly, and the site says typed search input is not uploaded.
Funding: Seeder is free and funded by ads and donations.
Maker: The About page identifies the maker as TrinTragula on GitHub; it does not state a headquarters or founding date.
Performance: Seed searches are CPU intensive and may slow the user's device; the maker says biome searches can be especially slow from Minecraft 1.18 onward.
Privacy: Seeder says it has no accounts or server of its own; saved worlds and locations stay in the browser, while Google Analytics and AdSense are used.
Saved-world limits: The browser can store up to 50 worlds and 200 locations per world, and the maker says users must export backups because browser data may be wiped.
