Privacy Policy
This policy explains how kuku handles information when you use Web3Deck. It covers the public website; the restricted administration system is not a visitor account service. Contact us using the email below for questions or requests.
Calculator inputs and wallet secrets
Calculations run in your browser. Our calculator code does not upload or save input values. Recovery phrase pages block network connections and exclude analytics and ads. Do not enter real wallet secrets on an online device or send them to us. Clearing displayed values does not guarantee secure memory erasure.
Storage on your device
Browser localStorage remembers theme, analytics choice, favorite tool IDs and recent tool IDs with visit times. Directory searches stay in browser memory or URL fragments. These preferences are not a server-side profile and are not sent to us by this feature. Clear site data or use the directory controls to remove them; clearing site data also resets your analytics choice.
Optional Google Analytics
Google Analytics 4 loads only after you allow analytics on ordinary pages. Google receives cookie identifiers, browser/device information and page visits, and processes network information under its own policy. Our configuration removes query strings, fragments and referrers from page-view data, disables Google signals and ad personalization, and does not send calculator inputs.
You can keep analytics off without losing tool access. Use the cookie settings button in the bottom-right corner to withdraw permission; this reloads the page if Google code is running and attempts to delete our domain’s Google Analytics cookies. Do Not Track and Global Privacy Control signals keep analytics off. Withdrawal does not automatically delete data previously received by Google; contact us about applicable rights.
External services and operational records
When you press Load in the Bitcoin backtest, your browser requests BTC/USDT daily prices from Binance; it receives your IP and request information, not your investment amounts through our request. Hosting and security infrastructure may process IP addresses, requested URLs, browser information, timestamps and errors to deliver pages and prevent abuse. Do not put secrets in URLs.
If you email us, we receive your email address and message to answer questions, investigate problems and handle privacy requests. Providing this information is voluntary; without sufficient information we may be unable to respond or identify relevant records. We may request proportionate identity verification for a privacy request, but never wallet secrets.
We also read Google Search Console reports about queries, impressions and clicks leading to this site to improve its content. These reports do not give us a visitor account or wallet identity.
Recipients, locations and retention
Information is used by kuku and service providers for the purposes above, or disclosed where required by law. The website is hosted in the United States; Google, Binance and email providers may process information in other countries under their own policies. We do not sell visitor personal information. Advertising is currently disabled.
Local preferences remain until removed, overwritten or cleared by your browser; recent-tool history is bounded by the directory’s storage rules. Contact and operational records are retained only while needed for support, security, dispute handling or legal obligations, then deleted or de-identified. Provider-held data follows the provider’s retention settings and policies. No single fixed retention period applies to all these categories.
Your rights and policy changes
Under applicable law, including Taiwan’s Personal Data Protection Act, you may request access or a copy, correction, cessation of collection/processing/use, or deletion of your personal data. Email kuku at the address below. Requests are handled subject to applicable statutory requirements and exceptions; these rights are not waived by this policy. We will update this page when processing changes and seek new consent where required.
