Dolzhenko DevIn short: the app collects no personal data. The diary, recordings and profile stay on the device; only subscription details leave it.
What the app does not do
It does not create an account, and does not ask for a name, a phone number or an email. There are no ads inside it and no data is sold. Cry recordings, the diary and photos never leave the device.
Third-party services
There are two. RevenueCat handles subscriptions and receives an anonymous identifier and the purchase details. AppsFlyer works out which ad brought you to the app: it receives device and advertising identifiers, and the bare fact that the app was opened, that the subscription screen was shown, that a trial was started or that a subscription was paid for. When a subscription is paid for, RevenueCat passes on the amount as well, so that what an ad brought in can be set against what it cost. If you decline when the app asks permission to track, the advertising identifier is not used. Cry recordings, the diary and photos are passed to neither of them.
That work exists in order to report back, so it is worth saying plainly: AppsFlyer tells the advertising network — for us that is Google — that an install, a visit to the subscription screen or a subscription came from its ad. What travels is the event, the campaign it belongs to and, for a paid subscription, the amount. Nothing about your child and nothing from the diary goes with it, and there is no name or account to send, because the app never asks for one. Apple also sends the networks an aggregated, anonymous report of its own; in it the app marks only which of these steps happened. Both services are required by contract to protect what they receive at least as well as this policy describes.
Their own privacy policies: RevenueCat and AppsFlyer. If other services appear in the app — advertising, for example — this section will be updated before they start working.
The microphone
Access to the microphone is needed only to record crying. The recording lasts about five seconds, is processed on the device and is deleted right after the analysis. It is not saved in the app and is not sent anywhere.
Without microphone permission the rest of the app works as usual.
Photos
You can add a photo of your child to the profile. It is picked through the system's own window, which hands the app a single image and gives no access to the rest of the library — which is why the app never asks for permission to your photos. The picture is reduced to a small square and kept in the app's folder next to the diary. It is uploaded nowhere and is deleted together with the profile.
Notifications
The app can remind you about a feeding, about bedtime, about the next sleep window, about a new article and about a milestone that has come due. Which of them are on is up to you, and all of them can be switched off in the app or in the iOS settings.
The reminders are put together on the device and shown by the system on a schedule. There is no server behind them: nothing is sent to us for a reminder to happen, and nothing leaves the phone at the moment one appears.
What is stored on the device
The profile of your child — name, date of birth, sex, weight, and a photo if you added one. The diary: sleeps, feedings, diapers, solids, temperature and growth. Along with those, the milestones you marked, favourite sounds, saved articles, the results of cry analyses and the conversation with the assistant. Much of this is information about a child's health, and that is exactly why it stays where it is: all of it sits in the app's protected folder and is available only to the app.
Your control
The data can be exported to a file or deleted entirely in the Data and privacy section. Until you do that it simply stays on the device: there is nothing on our side to expire, because we keep no copy. Deleting the app erases everything at once. Permission to track can be withdrawn at any time in iOS Settings, under Privacy & Security → Tracking. If you would like us to ask RevenueCat and AppsFlyer to delete what came from your device, write to support@dolzhenkodev.com and we will do it and confirm.
When we have to disclose
What is described above can be disclosed in three cases: when the law requires it — a court order or a similar legal process; when disclosure is needed in good faith to protect someone's rights or safety, to look into fraud, or to answer a request from a government body; and to contractors working on our behalf, who make no independent use of what they receive and are required to follow this policy. There are no other cases.
Security
The entries sit in the app's own storage, which only the app can reach, and are protected by iOS itself. What goes to RevenueCat and AppsFlyer travels over an encrypted connection. Nobody can promise complete protection and we will not either: it is worth keeping a passcode on the device and not handing it to strangers.
Children
The app is for an adult: it is made for a parent, not for a child. We do not knowingly collect personal data from children under thirteen and do not market to them. If it turns out that such data reached us anyway, we delete it at once. If you are a parent and believe this has happened, write to support@dolzhenkodev.com.
Changes and consent
This policy may change — along with the app, or when the requirements change. The new text is published here and on the official site, where the page carries the date of the last change. By continuing to use the app you accept the current version; if it does not suit you, the app can be deleted, and that ends everything described here.
