This policy applies to our public website and to the Arcline app. It is effective 12 November 2026 and was last updated 12 November 2026, and it is part of our Privacy Policy.
Cookies, local storage and trackers: what they are
- A cookie is a small text file that a website asks your browser to keep, and that your browser sends back to that website with later requests.
- Local storage is a feature of your browser that lets a website keep a small piece of data on your device. Unlike a cookie, it is not sent to the website automatically. A page has to read it on purpose.
- A tracker is a script or similar tool that records what visitors do, often to build a profile of them.
We explain what we use so that you do not have to guess.
Our public website
- It sets no cookies.
- It has no advertising tools and no cross-site trackers.
- Like any web host, our hosting provider records ordinary connection logs (your IP address, the time and the page requested) in order to run and protect the site. The Privacy Policy says more.
- Typefaces are loaded from Google Fonts. See the section on Google Fonts below.
The app you sign in to
When you sign in, the app keeps one item in your browser's local storage:
| Name | Type | What it is for | How long it lasts | Needed? |
|---|---|---|---|---|
rankhigh_token | Local storage | A signed token that tells our servers which account a request comes from. The app sends it with each request so that you stay signed in. | It stops working about 12 hours after you sign in, and is removed when you sign out. | Strictly necessary. Without it you cannot stay signed in. |
- The app sets no cookies.
- It stores nothing else in your browser for analytics, advertising or tracking: no other local storage, no session storage and no browser database.
- The token is not shared with any other company.
Google Fonts
Our website and app use typefaces from Google Fonts. Your browser fetches them directly from Google's servers (fonts.googleapis.com and fonts.gstatic.com). That means Google receives your IP address, your browser details and the address of the page that asked for the font. Google handles that under its own privacy policy. We do not receive anything back about you.
If you prefer to avoid this, you can use your browser's settings, or a privacy extension, to block requests to those two addresses. The website and app still work: your browser shows a standard typeface instead.
The optional visitor tracker on your own websites
Website owners can add the Arcline visitor tracker to their own websites. It is separate from our public website and from the app.
- It uses no cookies and no local storage. Nothing is written to a visitor's device.
- It stops by itself if the visitor's browser sends Do Not Track or Global Privacy Control, and then nothing is stored.
- It does not store IP addresses. It uses them only to compute a pseudonymous code that changes every day.
If you add the tracker to your website, you are the Data Fiduciary for your visitors' data, and you must tell your visitors about it in your own privacy notice and follow the laws that apply to your website, including the Digital Personal Data Protection Act, 2023. What the tracker records is listed in the Privacy Policy.
Checkout and the customer portal (Polar)
If you buy Premium, you pay on a checkout page that belongs to Polar (polar.sh), our payment provider and merchant of record. You also manage or cancel your subscription in Polar's customer portal, which is on a polar.sh address too. Those pages are run by Polar, not by us, and Polar sets its own cookies there. We do not control them and this policy does not cover them. Please read Polar's policies on polar.sh.
- We set no cookies on our own website or in our app, before, during or after checkout.
- We receive only your subscription status, your plan and a customer ID from Polar. See the Privacy Policy.
- If you never open the checkout or the customer portal, none of Polar's cookies are set.
Links and other companies' sites
The app links to, and works with, services run by other companies, such as GitHub, WordPress, Ghost, Cloudflare, Google and Polar. When you visit their sites, or sign in to them, they may use their own cookies. We do not control those, and this policy does not cover them. Please read their policies.
Your choices
- Sign out. Signing out removes the sign-in token from your browser at once.
- Clear it yourself. You can delete a site's local storage from your browser's settings at any time. You will simply be signed out.
- Block it. If you block local storage for our app, you will not be able to stay signed in.
- Block Google Fonts. See the section above.
Changes to this policy, and contact
If we change what we store, we will update this page and its “last updated” date, and for anything beyond what is strictly necessary we will ask for your consent first. Questions: thescalelab10@gmail.com. Complaints: see Grievance Redressal and Your Data Rights. You can also contact us.
