Draft prepared by engineering — pending review by a lawyer before mainnet. It describes how arky works today, from its code, and will change before it is final. Text marked [to be completed: …] is information the operator has not supplied yet.
Cookies and storage
Draft of 24 September 2026
This page lists every cookie and every item arky keeps in your browser, taken from the app’s code. arky uses no analytics, advertising or tracking cookies and loads no third-party trackers. Its fonts are served by arky itself, not by Google.
Our finding, and why there is no consent banner
The one cookie in the system is strictly necessary, and so is almost everything below: it is what makes a feature you asked for work. Such storage needs no consent under the ePrivacy rules, so arky shows no banner.
One item is not strictly necessary: arky.visitor, a random ID used to count referral link clicks without counting the same browser twice a day. It is sent with the click; our servers store only a daily hash of it, with no IP address. [to be completed: counsel to confirm whether this is covered by the CNIL exemption for audience measurement; if not, ask consent before setting it, or remove it]

Kept in your browser
These stay on your device unless the purpose says otherwise.
| What | Key | Purpose | Lifetime |
|---|---|---|---|
| Your wallet, encrypted | arky-wallet | IndexedDB. The self-custodial wallet itself. Clearing site data deletes it: keep your recovery phrase. | Until you clear site data |
| Your sign-in token | arky.session.* | Session storage. Keeps you signed in across a reload of the same tab. | Until the tab closes |
| Terms acceptance | arky.terms.accepted.* | Which version of the terms each wallet accepted in this browser, and when. | Until you clear site data |
| The getting-started guide | arky.onboarding.v1* | Whether the guide was seen or finished, so it is shown once. | Until you clear site data |
| Layout and preferences | arky.layout.*, arky-list-order, arky-trade-settings | How you arranged the windows; list order; quick-buy amount and slippage. | Until you clear site data |
| Lists and alerts | arky-watchlist, arky-price-alerts, arky-tracked-wallets, arky-copy-configs | Your watchlist, price alerts, followed wallets and copy-trading settings. | Until you clear site data |
| An open deposit | arky.depositHub.open | The cross-chain deposit you started, so it survives a reload. | Removed when the deposit completes |
| A referral code | arky.ref, arky.ref.bound.* | The code from the link you arrived with, sent when your wallet connects so the referrer is credited; then whether that was done. | Until you clear site data |
| A visitor ID | arky.visitor | Counts referral clicks (see above). Not strictly necessary. | Until you clear site data |
| Wallet connection | wagmi.* | The wallet library remembers which wallet you connected last. | Until you clear site data |
| A launch you just made | arky.launched.* | Session storage. Shows your new token once. | Until the tab closes |
If you connect Coinbase Wallet, its own software stores data under keys starting with -CBWSDK. Settings in the app lists every arky item and its size.
Removing them
You can clear cookies and site data in your browser settings at any time. Doing so signs you out and removes the wallet from this browser — make sure you have your recovery phrase first. See also the privacy policy.
