Effective date: October 2026. This note explains how the mobile apps handle information. It is written for the person holding the phone. The short version is easy to keep: the apps do not build a personal profile, people do not send personal data to each other, and the only identifier relied on is a unique id used for attribution and push.
The products are made for iOS and Android. They can include an in-app assistant that talks with you. They do not assemble a portrait of your life, and they do not open a path from your data to someone else’s phone. If a sentence below and a screen in the app ever seem to disagree, write to the studio and ask. The written note is the account you should trust.
Singular
Attribution uses Singular. Attribution means learning which route led to an install or an open: a campaign, a link, or another measured source. Singular receives the unique id and the attribution signal tied to that install. That is the job. It is not a biography.
Singular does not receive your name, your email address, your phone number, your contacts, or your precise location from these apps, because the apps do not collect those things in order to describe you. We do not add those fields beside the unique id to make the attribution call “more complete.” A route is not a person. Singular is also not a bridge to other users. It measures how an install arrived, and then that measurement is finished. It does not introduce you to anyone, and it does not carry a message you wrote.
OneSignal
Push notifications use OneSignal. A push is a short notice sent to the device, for example that something inside the app has changed. OneSignal uses the unique id to address that device. The id is how a notice finds the install. It is not a name you chose, and it is not a handle other people can search.
The app does not hand OneSignal a personal profile. No name, email, phone number, contact list, or precise location is attached to the push record. A notification is not a message from another user, and it is not a way for users to reach each other. If a notice arrives, it came through the push path, not through someone else’s inbox. You can ignore it. It does not open a social layer that this note has said does not exist.
The assistant
The in-app AI assistant can talk with you. It is not a human. Nobody from the studio is sitting behind that conversation and typing a reply. It is software that answers inside the app. Treat it as software.
It is not professional advice. It is not legal advice, medical advice, financial advice, or any other kind of licensed counsel. Use it to ask what a screen is doing. Do not use it as a specialist, and do not use a reply to make a decision that needs a qualified person. If the answer sounds confident, confidence is not a credential.
What you write is used only to answer you. The text is there so a reply can be formed. It is not passed to other users. It is not posted into a shared feed. It is not used to assemble a profile that other people can browse. The assistant is a closed turn: your words in, a reply out, and no audience in between. If you want a person at the studio, send an email. The assistant cannot take that role, and it should not be asked to pretend.
No exchange between users
Users do not send personal data to each other through these apps. There is no user directory, no shared profile, and no transfer of one person’s assistant messages to another person. The paths run outward from your device: to Singular for attribution, and to OneSignal for push. Between those paths and another person’s device there is a gap on purpose.
Nothing in the product is designed to close that gap. There is no “find a friend,” no contact upload, and no thread where two people trade details. If you are looking for a place to send someone your phone number, this is not that place, because the app does not have it and does not ask you for it.
No personal profile
The apps build no personal profile. They do not ask you for your name, your email address, your phone number, your contacts, or your precise location in order to describe who you are. They do not combine those pieces, because they do not take them. You can use the app without turning yourself into an account full of identity fields.
A profile, in the ordinary sense, is a record that says who someone is and how to reach them. That record is not part of this product. The unique id below is not a substitute biography. It does not stand in for a name, and it is not enriched later with the fields this section refuses.
The unique id
The only identifying item is a unique id. It lets Singular tell one install from another for attribution. It lets OneSignal address a device for push. It is an identifier for the install, not a name you go by. It is not an email address and it is not a phone number. It is not shown to other users as a way to find you, message you, or exchange data with you.
If you delete the app, you take the install with you. The id is not a lasting public identity, and it is not published. It exists so the two services named above can do their narrow jobs. When this note says “the only identifying item,” it means there is not a second, quieter identifier — not a contact card, not a precise map pin, not an address book — waiting behind the id.
Email to the developer
If you email the developer, that message is ordinary mail to the studio. It arrives as correspondence, the way a letter arrives, and it is read so the studio can answer. It is not folded back into the app as a profile field.
Write to CIRRUS AERO LTD at [email protected]. The same address is on the Contacts page. Your email is not added to an in-app profile. It is not sent to other users. It is not part of Singular attribution, and it is not part of OneSignal push. Please do not include documents you would not put in a normal letter. The form on the Contacts page only opens your own email app. It does not deliver the note to a server of ours.
Changes
If this note changes, the new text replaces what you see here, and the effective date at the top changes with it. October 2026 is the date of this version. Check the date when you come back. The version with the current date is the one that applies. An older copy saved somewhere else is not a second policy. The page you are reading is the source.
A change will not quietly invent a personal profile or a path between users. If the facts in this note ever need to move, the new wording has to say so in the open, under a new date, where you can read it before you continue.
Contact
Questions about this note go to the developer. The same facts are written, in the language of use and disputes, in the Terms. Contacts holds a short card and a form that opens your email app with your note prepared locally.
