Cointikka is a free toolkit for Bitcoin holders and Bitcointalk users. This page explains, in plain language, what data the app touches, where it's stored, and which outside services it talks to.
Cointikka does not run its own user accounts, does not require sign-up, and does not have a backend database that stores your personal data. Your stats (username, activity, merit, posts, goals, streaks, theme preference) are saved only in your own browser, using the browser's local storage. We never see it, and it never leaves your device unless you export or share it yourself.
The one exception: when you look up live data (your Bitcointalk stats, BTC prices, blockchain data, crypto news), that request is sent out to the relevant public service, sometimes routed through our own lightweight relay to avoid browser restrictions. Details on exactly what that involves are in Section 4 and 5 below.
Depending on which tools you use, you may voluntarily enter:
All of this is information that is either already public on the Bitcointalk forum (your forum stats) or data you choose to type in for the calculators/tools to work. We do not ask for your real name, email, physical address, or payment details anywhere in the app.
Cointikka is a client-side, browser-only application. Everything described in Section 2 is written to your browser's localStorage — a storage area that belongs to your device and browser profile, not to a Cointikka server. We have no database, no login system, and no way to view what you've entered unless you choose to show us (for example, by screenshotting a page and sending it to us via Bitcointalk DM or Telegram for support).
Because storage is local, your data does not sync across devices or browsers, and it will be lost if you clear your browser's site data, use a private/incognito window, or switch browsers.
To provide live data, Cointikka's pages make requests directly from your browser to the following public services. Each of these services may log standard technical information (such as your IP address) as part of normal web traffic — this happens under their own privacy policies, not ours, since we don't operate these services.
| Service | What it's used for | Data sent |
|---|---|---|
| Bitcointalk.org | Fetching your public activity/merit/post stats when you enter a UID | The UID or username you provide, and the request itself via relay |
| mempool.space | Live BTC price, blockchain explorer lookups (addresses, transactions, blocks), fee estimates | Whatever address/txid/block you search for direct |
| CoinGecko | Historical BTC prices (DCA/Tax/Profit calculators), market mover data | None personal — public price data only via relay |
| open.er-api.com | Fiat currency conversion rates (160+ currencies) | None personal direct |
| Google Fonts | Loading the Inter, Space Grotesk, and JetBrains Mono typefaces | Standard font-request technical data direct |
None of these lookups require you to identify yourself beyond what you choose to type into the search/UID field, and none of the data returned by these services is sent to us or stored anywhere except your own browser (Section 3).
Some services above — Bitcointalk and CoinGecko — don't allow browsers to request data from them directly (a security restriction called CORS). To make those lookups work, Cointikka routes those specific requests through a small relay we operate (btt-proxy.cointikka.workers.dev), which simply forwards your request to the destination and returns the public response. The relay does not store, log, or retain the requests that pass through it beyond what's necessary to serve the request in real time.
If the relay is ever unreachable, the app falls back to a public third-party CORS proxy to keep the lookup working — the same "forward and return" behavior applies.
Cointikka does not use cookies for tracking. It uses browser localStorage to remember your settings and stats between visits. The keys it may create are:
btr_profile_v4 — your saved Bitcointalk statsbtr_goals_v4 — your custom and daily goalsbtr_streak_v4 — your sync-verified activity streakbtr_merit_history_v1 — a history of your synced merit/activity snapshots, used for trend chartsbtr_theme_v1 — your selected color themebtr_sidebar_collapsed_v1 — whether the sidebar is collapsedbtr_news_cache_v1 — a short-lived cache of news headlines, to avoid refetching on every visitYou can clear all of these at any time using the in-app ⏻ Logout button, or by clearing your browser's site data for this domain.
Cointikka may display advertisements served by Google AdSense and/or similar ad networks to help cover the cost of running the site. These networks may use cookies or similar technologies to serve relevant ads and measure ad performance, in accordance with their own privacy policies. You can learn more about how Google uses data from partner sites at policies.google.com/technologies/partner-sites, and you can opt out of personalized advertising through Google Ads Settings.
Cointikka is not directed at children and is not intended for use by anyone under the age of 13 (or the relevant minimum age in your jurisdiction). We do not knowingly collect data from children.
Because everything is stored locally, you're always in control:
We may update this page from time to time as the app's features change. The "Last updated" date at the top will always reflect the most recent revision. Continued use of Cointikka after a change means you accept the updated policy.
