Privacy Policy
Last updated: 21 October 2026
OwnDay is a personal timeline app. It records where you go and what you're doing, entirely for your own use. This policy explains exactly what OwnDay collects, why, and — most importantly — what happens to it.
OwnDay stores your archive on this device and has no OwnDay server or account. Apple Maps lookups, optional Apple Weather lookups, and files you choose to export or share are exceptions, described below. Nothing is sold or shared with advertisers or analytics companies, and OwnDay does not track you across other apps or websites.
OwnDay also lets you type a free-text note on any visit, and tag the people who were with you by name (a small, reusable list you build up on your own device — not your Contacts). Both are stored exactly like everything else on this page: only on your iPhone, never uploaded, never used for advertising or analytics. A name you tag is a record you're choosing to keep about someone else, not just about yourself, so add one only where you're comfortable keeping that on your own device.
All of the above is stored in a local database inside the OwnDay app on your device, protected by iOS's own file encryption. OwnDay has no backend, no account system, and no cloud sync of its own. Apple Maps lookups, Apple Weather lookups (only if you turn on Visit Weather), and files you choose to export or share, all described below, are the only ways any of this data leaves your device.
iOS's own device backup (iCloud Backup, or a computer backup made through Finder or Apple Configurator) can include OwnDay's local data along with the rest of your iPhone's apps, the same as it would for any other app, unless you've excluded OwnDay or turned off backups for your device. OwnDay does not control or add to this — it is Apple's system backup, governed by Apple's own iCloud & privacy terms, not OwnDay's.
To turn a raw location into a place name ("Home", a café, an office), OwnDay asks Apple Maps to look up nearby places for a coordinate you visited. When you manually search for a place by name — for example while adding or correcting a visit — the text you type is sent to Apple Maps the same way, to find matching places. Either lookup is handled by Apple's MapKit framework under Apple's own Maps & privacy terms — OwnDay's developer never sees or receives this data.
Visit Weather is off by default. If you turn it on in Settings, OwnDay asks Apple Weather (WeatherKit) for the weather around the start of a visit, walk, workout or sleep, and for the weather right now at your current stop. The request contains only an approximate location, rounded to a grid of roughly 5 km, and the hour or time range of the visit; it never contains your recorded coordinates, place names or notes. Apple handles the request under Apple's own WeatherKit privacy terms, and OwnDay's developer never sees it. The weather that comes back is saved with the visit on your device and is included in your backups; turning Visit Weather off stops new lookups. No other network requests are made by OwnDay.
"Ask OwnDay" and the optional "Help fill this gap" suggestion in Add Visit use Apple's on-device Foundation Models framework — part of Apple Intelligence, on iPhones that support it. Your question, or the nearby recorded context OwnDay already has, is processed entirely on your device; none of it is sent to Apple, to OwnDay's developer, or to any other server. The model only ever chooses which of OwnDay's own built-in answers to show, or which existing evidence to suggest — it never invents a fact about your history, and it never saves anything on its own: every suggestion still needs your own tap to accept it. If Apple Intelligence isn't available or turned on, both features say so plainly, and the rest of OwnDay works exactly the same without it.
You can create a local backup file from within OwnDay at any time. The file is a readable JSON snapshot of your recorded data. It is created on your device and stays there unless you choose to save or send it somewhere — for example, using iOS's own Share Sheet to save it to Files, iCloud Drive, or email it to yourself. OwnDay never uploads a backup automatically.
OwnDay's own temporary sharing copy becomes eligible for cleanup after 24 hours; cleanup runs the next time OwnDay performs a cleanup pass, and iOS may remove the copy sooner. A copy you save or share is outside OwnDay's control: it follows the retention, access, and deletion rules of the service or person that receives it. OwnDay cannot recall or delete that copy, and it does not add a password or its own portable-file encryption after you share it.
OwnDay's Diagnostics screen can generate a troubleshooting report for your own use — for example, to attach to a support email. By default, that report is redacted: it contains only aggregate timings, counts, the app version, and your device/OS class. It never includes coordinates, place names, notes, or Health values.
An explicit "Include detailed local evidence" toggle, which you must turn on yourself, opts into a more detailed report that also lists the retained events' own text. That text stays generic except for a few location-resolution lines, which can name places or distances if you've separately turned on detailed location diagnostics in Settings, and — if you've turned on Calendar as corroborating evidence — a line naming a matched calendar event's title. This detailed mode is meant only for troubleshooting a problem you're actively reporting.
Either way, nothing leaves your iPhone automatically — OwnDay has no server. A report is only shared if you choose to copy or send it yourself. OwnDay's own temporary copy of it becomes eligible for cleanup after 24 hours; cleanup runs the next time OwnDay performs a cleanup pass, and iOS may remove it sooner.
Because everything lives only on your device, you are always in complete control of it. You can erase all recorded data from OwnDay's Settings at any time. Deleting the app removes OwnDay's own local data, since there is no server copy to separately remove — but it does not reach a backup, export, or shared copy you already saved elsewhere; each of those is deleted separately, at its own location, the same way you'd remove any other file you saved there.
You can revoke Location, Motion & Fitness, or Health access at any time from iOS Settings → Privacy & Security (or Settings → Health → Data Access & Devices → OwnDay for Health specifically). OwnDay keeps working with whatever access remains; it never re-prompts beyond what iOS itself allows.
OwnDay contains no advertising, no analytics SDKs, and no third-party tracking of any kind. It does not use the Advertising Identifier (IDFA) and does not track you across apps or websites.
OwnDay is not directed at children and is not knowingly used to collect data from anyone under 13.
If OwnDay's data practices ever change, this page will be updated and the "last updated" date above will change accordingly.
