Access the browser app
The tracker is available at this website's /app/ address. This information site does not store child records; there is no App Store or Play Store download.
Open the tracker in your browser. Installation is optional; on iPhone Safari, use Share then Add to Home Screen if offered. Otherwise use a normal browser tab. An initial online visit is required before any offline app-shell access, and offline use is not guaranteed.
Records belong to one browser profile and website address. Browser storage can be cleared. Export your records and saved photos to a file you control before changing devices, browsers or addresses; check that the file can be imported. Language and theme settings are not included.
Synthetic Chromium browser capture of the tracker, not a hosted app or a physical-device test.

Frequently Asked Questions
Answers about browser storage, manual file recovery and optional installation.
The tracker stores entered records in IndexedDB for its browser profile and website address. This information site is not a record app. Hosting receives request metadata; see Privacy and browser storage below for details.
No. A PC, phone or another browser does not automatically share records. Export a file yourself and keep it somewhere you control; verify an import before relying on it. There is no automatic cloud backup.
The current versioned CSV export includes profiles, logs and saved photo bytes; language and theme settings are excluded. Import previews a file before you choose to merge or replace records. A saved file is not a guarantee of recovery.
Privacy and browser storage
Notice version: 18 October 2026.
Operator and privacy contact: Norbert Parti, Szeged.
The tracker is for adult caregivers. Profiles, logs and saved photos are stored in your browser, not an Acorn record server. There are no Acorn accounts or automatic device sync. A local child ID in a page URL cannot retrieve the child's records from the server, but can link requests for the same item.
The tracker uses IndexedDB for records and settings and Cache Storage for static offline files. This information site uses localStorage for language and theme: language is saved at startup and on a language change; theme is saved when you choose it. This information site's code includes no advertising or analytics scripts. Browser storage is not all cookies, and clearing site data can remove records and preferences together. See the storage, recovery and deletion guides below.
Cloudflare Workers Free delivers the site and tracker. Requests expose technical information such as IP address, URL and timestamp to the hosting provider. The operator has enabled observability and persisted invocation logging for troubleshooting. This does not upload the browser database or guarantee that every static request creates an invocation log.
As checked on 18 October 2026, Cloudflare documents 3-day Workers Logs retention on Free and announces 7 days from 1 December 2026. These provider-defined periods are not a custom deletion setting or a retention limit for every Cloudflare dataset. The linked provider references describe the current terms.
If you email support, the operator and mail providers receive your sender address, subject, message and other email metadata to handle your request. Proton Mail is used for support. The operator deletes resolved correspondence from the mailbox, including Trash, within 90 days after resolution. Do not send child records, photos or exports. This deletion does not erase your copies or guarantee deletion from provider backups.
For the operator's use of technical request information and support correspondence, the legal basis is legitimate interests (GDPR Article 6(1)(f)): delivering and securing the site, troubleshooting failures and answering voluntary support requests. This is not permission to upload browser-local child records. You may object to this processing using the contact email.
For personal data the operator processes, contact the email below to request access, correction, deletion, restriction or portability where applicable, or to object. Rights depend on applicable law and the processing concerned. The operator cannot remotely access, delete or restore your browser-local database; use the tracker and browser controls. You may lodge a complaint with Hungary's data protection authority, NAIH.
Cloudflare describes international processing, including outside the EEA, and its transfer safeguards in its privacy policy. Proton's Mail privacy policy describes email metadata, processing locations and provider backups. These provider policies are separate from the operator's mailbox-deletion practice; this site does not promise EU-only processing or zero provider retention.
Profiles, logs, saved photos and tracker settings stay in IndexedDB for this website address and browser profile. The information site and tracker share the same origin; their different paths do not isolate browser storage. The site also saves language and theme preferences.
The offline app-shell cache contains static files, not a record backup. Clearing site data, private mode, storage pressure or browser policy can remove records. Persistent-storage permission is not a retention guarantee. There is no automatic cloud backup or device sync.
Export and recovery
In the tracker, open Data and settings and export a CSV file you control. It can contain profiles, logs and saved photos, but not language or theme settings. Protect the file and do not send it to support. Saving it in your own cloud drive does not enable automatic Acorn sync.
Use Import in Data and settings to choose a file and inspect its preview before merging or replacing records. Export existing records before replacement. Check that your saved file imports before clearing data or changing browser, device or website address. A file is not a guarantee of recovery.
Delete local records
Open a child profile and choose Remove child to delete its current records. This does not erase exported or shared files, copies on other devices, or legacy storage copies that older installations may retain after migration.
To clear this website's local data, first export anything you need, then use your browser's clear site data control. This can remove tracker records, site preferences and offline files together. Delete exported copies separately wherever you saved or shared them. The operator cannot remotely delete or restore your browser-local database.
Need help or have feedback?
Email the operator with your app version (if known), browser and operating system versions, steps to reproduce, and what you expected versus what happened. Use fictional examples; do not send child records, photos or exported files.
If no email app opens, copy this address into your email service:

You must send the message yourself. This page cannot send email or confirm delivery.
The operator receives support email through Proton Mail and deletes resolved conversations from the mailbox, including Trash, within 90 days after resolution. This does not delete your own copies or guarantee deletion from provider systems.
