Privacy

Last updated October 19, 2026

The short version: we don't sell your data, we don't run ads, and we don't use tracking cookies. Most of our tools keep your data on your own device. Email hello@arikico.com with any question, or to have anything we hold about you deleted.

Ariki Co. is two people who build small software tools. This page covers this website and each of our tools. "We" and "us" means Ariki Co.

This website

The site is hosted on Cloudflare, which handles your IP address and basic request details to deliver the pages and protect them from abuse.
We may count visits with Cloudflare Web Analytics, which uses no cookies and does not identify you.
Fonts load from Google Fonts, so Google sees your IP address when the page loads.
The site sets no cookies and has no ads or third-party trackers.

Email

Mail to an arikico.com address is forwarded by Cloudflare to our personal inboxes (Gmail). We keep messages so we can reply and follow up, and we never share them for marketing.

TCGGEZ

TCGGEZ has its own privacy policy at app.tcggez.com/privacy.

TCG Bulk Check

TCG Bulk Check runs on your own computer. It downloads public card prices and recent sales from TCGplayer and tcgcsv.com, and keeps its cache and your settings on that computer. It sends nothing to us.

Seller extensions

The extensions run in your browser. They read the TCGplayer, Mercari and eBay pages you open, so they can fill in forms and keep track of your listings, quantities and sales.
What they record (items, prices, quantities, sales, fees and photos) is stored in your browser's extension storage. It stays there unless you turn on team sharing.
Team sharing is optional. If you sign in with your email and join a group, those same records are stored on TCGGEZ's servers (on Cloudflare) so everyone in your group can see them. You can sign out at any time and ask us to delete the group's data.
The extensions have no analytics and never list, buy, end or message anything on your behalf.

Daikonbun

During the private beta, Daikonbun runs on your own machine or server, and your boards and cards stay there. If you join the launch list on daikonbun.com, your email address is stored with Buttondown, our newsletter service, and you can unsubscribe from any email.

Children

Our tools are not made for children under 13, and we don't knowingly collect their information.

Changes

If this changes, we'll update this page and the date at the top.
