Effective October 2026
This note is the privacy chart for apps made by KEPLER WOLF LIMITED. It is written for the person holding the phone. Read it as a map of what the apps are allowed to touch. The date above is the effective date of this text. The studio builds the software. The software does not build a portrait of you.
The chart records tasks, screens, and the replies an assistant can give. It does not record a life. A mark goes on the chart only when the app needs it to attribute an install, to deliver a push you allowed, or to answer something you just wrote. Everything else stays blank on purpose. A blank is easier to trust than a paragraph that promises to be careful with facts the product never needed.
Singular
Attribution uses Singular. When an app is installed or opened, Singular receives a unique id so the studio can see which listing or campaign the install came from. That is the whole job of attribution: to connect an install to a source, not to connect two people. Singular is not a meeting place. It is not given your name, your email, your phone number, your contacts, or your precise location. The identifying item it receives for this work is the unique id.
The studio does not use Singular to watch where you walk, who you know, or what you type to the assistant. A campaign report can say that an install happened. It cannot say who you had lunch with. If a future build needed a new kind of mark for attribution, this note would have to name that mark in plain language before the app relied on it. Until then, the line stays where it is: Singular, a unique id, and nothing that reads like a dossier.
OneSignal
Push notifications use OneSignal. If the app asks to notify you and you agree, the operating system issues a delivery token for that device. OneSignal receives that token together with the unique id, and it uses them to carry a short message from the app to the device. A push is not a note from another user. OneSignal is not given a personal profile. Turning notifications off in the system settings stops delivery. The app does not read your contacts in order to push them, and it does not ask OneSignal to assemble a list of people you know.
A notification can remind you of a task inside the app. It cannot introduce you to someone else who installed the same product. The token is a doorbell for one device, not a directory. If you never allow notifications, there is no doorbell to ring, and OneSignal has nothing useful to deliver. The choice sits in the operating system, where you can change it later without writing to the studio first.
The assistant
The in-app assistant can talk with you. It is not a human on the other side of the glass. It is not a lawyer, a physician, an accountant, or any other professional, and a reply is not professional advice. You may ask it about the tasks the app is built to handle. What you write is used only to answer you. Those words are not passed to other users. They are not folded into a profile that follows you from person to person.
The assistant can be wrong, incomplete, or oddly sure of itself. Choices that matter stay with you. Do not treat a reply as a verdict, and do not use it for emergencies or for decisions where a wrong sentence would harm someone. Do not send the assistant anything you would be unwilling to have processed for the sake of a reply. The processing exists to produce that reply. That is the end of its job inside the product. The same limits apply on iOS and on Android, because the assistant is part of the shared plan, not a feature that one platform quietly widens.
No exchange between users
The apps are not a pipe from one person to another. There is no shared inbox, no directory of users, and no control that sends your words, your unique id, or your pushes to someone else using the app. What you tell the assistant stays in the service of your own answer. Another person's install is another ring. The rings do not trade contents. Users do not send personal data to each other, because the product has no lane for that sending.
If you are looking for a place to meet people, message a contact, or hand someone your phone number, this is the wrong instrument. The chart does not include that lane, and the studio will not add it under a softer name. A reply from the assistant is not a message you asked the app to forward.
No personal profile
The apps build no personal profile. They do not ask for your name, your email, your phone number, your contacts, or your precise location, and they do not combine those facts because they do not take them in order to describe you. A blank here is a decision, not a missing screen. You can use the product without handing over an address book or a pin on a map.
The studio can still attribute an install and deliver a push, because those jobs use a unique id rather than a dossier. Nothing in the app asks you to "complete your profile." There is no profile to complete. If a screen ever requested your name, your inbox, your phone number, your contacts, or a precise place, it would be outside this note, and this note would be wrong until it was rewritten. The text you are reading is the boundary.
The unique id
The only identifying item is a unique id. It is a string made for the install. Singular uses it for attribution. OneSignal uses it, with the system push token, to deliver notifications you allowed. It is not your name and it is not a phone number. It does not point at your contacts or your precise location. It does not let one user look up another.
Remove the app, and the id tied to that copy is no longer a way to reach that copy. The studio does not treat the id as a personality, a login, or a thing you can sell. It is a mark on the chart so two narrow jobs can be done: attribution through Singular, and push through OneSignal. Those are the jobs. They are not a pretext for collecting the rest of a person.
Emails to the developer
If you write to the studio, you do it from your own mail app. The developer is KEPLER WOLF LIMITED and the address is [email protected]. An email contains what you chose to put in it: your address, your name if you added one, and the message. That correspondence is how a person at the studio reads and answers you. It is kept as mail. It is not written back into the app's unique id, it is not sent to Singular or OneSignal as a profile, and it is not shared with other users of the app.
The form on the contacts page only opens your mail app and fills the subject and body. This site has no server waiting to store the form. If you do not want to use the form, the address above is enough. Write as much or as little as you decide. The studio cannot see a message you never send.
Changes
The studio revises this note when the apps change, when the role of the assistant is narrowed or widened, or when the way a unique id is handed to Singular or OneSignal has to be described differently. The effective date at the top is the date of the text you are reading. The page itself is the current note. A change appears in the sentences, where you can read it, rather than in a hidden switch. If you keep an older copy, compare the date before you rely on it.
Contact
Questions about this note go to the developer, KEPLER WOLF LIMITED, at [email protected]. Name the app if you have one in hand, and write in ordinary language. The studio answers by email. The privacy chart is the same on iOS and Android, because every product is one plan for both platforms. The terms describe acceptable use and how a dispute is raised. They do not quietly permit a profile this note refuses.
