Kepler

Privacy

Last updated 2 August 2026

Kepler has no accounts, no sign-up and no login. It does not ask for your name, your character, or your payment details, and there is nothing here to sell. The only place you can give us an email address is a bug report, where the field is optional and may be left blank. The route you build stays in your browser unless you deliberately choose to share it or send us a report.

What stays on your device

Your routes, group composition, talent selections and interface preferences are saved in your browser's local storage. They are never sent anywhere. Clearing your browser's site data for this site erases all of it permanently, and nobody — including us — has a copy.

The planner also keeps a small local record of how smoothly the map rendered, so that if it ever performs badly there is something to look at afterwards. That record stays on your device and is never transmitted.

Share links — the one thing you can choose to send

When you press Share, the plan you are looking at is sent to us and stored so that a link can point at it. That is the only time anything you make leaves your browser.

What a shared plan actually contains: the dungeon, the specializations in your group, the talent selections, and which enemies are in which pull. It is rebuilt from a fixed list of permitted fields before it is stored, and there is no field anywhere in it that accepts free text. You cannot put a message, a name, or any other writing into a shared plan, because the format has nowhere to hold one.

Two consequences worth being clear about. Anyone with the link can open the plan — the link is the only key, so treat it as public once you have pasted it. And a shared plan cannot be edited or deleted afterwards. Each one is stored permanently and unchangeably by design, so that a link you gave someone keeps working. Sharing again creates a new, separate link rather than altering the old one.

If you would rather not send anything at all, Export produces the same plan as a piece of text you can paste anywhere yourself. It never contacts us.

Bug reports — the other thing you can choose to send

The planner is in beta and carries a form for telling us when something is wrong. Using it is entirely optional, and nothing is sent unless you press Send report.

What a report contains: what you typed, plus the dungeon and keystone level you were viewing, how many pulls were in your route, which data build you were on, your browser's identification string and your window size. That list is complete, and the form itself shows it to you before you send anything.

The contact field is optional. Leave it blank and your report reaches us with nothing that identifies you. It exists only so we can reply if you would like one, and whatever you put in it is used for that and nothing else. We never require an email address to accept a report — that is the whole reason the form exists rather than an email link.

Because the text is yours to write, please do not put anything sensitive in it. Reports are kept for 90 days and then deleted automatically, and they are readable only by the site's owner through a page that requires signing in. As with share links, filing a report is rate-limited by network address and checked by Turnstile.

Your IP address

Like every website, ours sees the network address your request arrives from. We use it for one purpose: to limit how many share links and bug reports can be created from a single address in a short period, so that one person cannot flood either service. It is used at the moment of the request and we do not store it alongside your plan or your report, or build any profile from it.

Bot protection

Creating a share link is checked by Cloudflare Turnstile, which confirms the request came from a person rather than an automated script. It runs invisibly — there is normally nothing to click, and no puzzle to solve. To make that judgement, Cloudflare receives signals from your browser such as your network address and browser details. It is not used to build an advertising profile and does not follow you around the web.

Turnstile is operated by Cloudflare on our behalf. Its data handling is described in the Cloudflare Turnstile Privacy Addendum, which supplements the Cloudflare Privacy Policy.

Analytics

We use Cloudflare Web Analytics to see roughly how many people visit and how quickly pages load. It does not use cookies, does not fingerprint your device, and cannot follow you to other websites. What it reports is aggregate: page views, approximate country, browser and loading speed. It is not linked to anything you build or share.

Advertising

The route planner carries two clearly labeled advertising panels — one in each side column, both marked ADVERTISEMENT. They are the only advertising anywhere on the site, they never cover the map or the tool, and the tool works identically whether or not they load.

When ads are being served, they come from Google AdSense. To pick and deliver an ad, Google receives the ordinary details of the request from your browser — your network address, browser details, and the fact that the ad appeared on this page — and may use cookies or similar identifiers, which can mean personalized ads depending on your own Google settings and your region's rules. That data goes to Google under how Google uses information from sites that use its services; you can adjust or opt out of personalization at Google's Ads Settings.

If you use an ad blocker, the panel shows a short note asking you to consider allowlisting the site instead — nothing is hidden, broken or slowed down in response. The blocked state and the ad state are the same size by design, so the tool never shifts around you either way.

Other services your browser contacts

Very little. Every image, map, icon and typeface is served from this site, so loading a page does not announce your visit to anyone else. The outside requests are:

The typefaces used to be loaded from Google Fonts, which meant every page view sent your network address to Google. They are now served from this site instead, so that no longer happens. Outside the two labeled ad panels, no game-data service, image host or advertising network is contacted from your browser at any point.

Cookies

We do not set any cookies of our own. Cloudflare may set a cookie strictly to operate the bot protection described above, and while the site is still in closed testing, signing in as an invited tester also sets a session cookie for that purpose. The one advertising exception is the two labeled ad panels: while ads are being served, Google may use cookies or similar identifiers there as described under Advertising, including for personalization where your settings and region allow it. Nothing else on the site uses cookies for advertising or tracking.

Children

Kepler is a tool for players of a video game and is not directed at children under 13. We do not knowingly collect information from them — and, as above, we ask for no personal information from anyone. The single exception is the optional contact field on a bug report, which is yours to fill in or leave blank, and which we would rather you left blank if you are under 13.

Contact

Questions about this policy — or anything else about the site — go to [email protected]. That address exists for this site alone: writing to it does not subscribe you to anything, and the address you write from is used only to reply to you.

Changes

If this policy changes in a way that affects what is collected, the date at the top will change with it. Material changes will be noted on the site rather than made quietly.
