Fog Log collects nothing. It has no account, no analytics, and no advertising. It makes no network requests of any kind — there is no server to send anything to, because there is no server. Everything you enter stays on your device until you choose to send it somewhere yourself.
Everything you type into Fog Log is written to a database on your own device. That includes:
This information is not transmitted anywhere. The developer cannot see it, and has no way to see it. If you delete the app, this information is deleted with it.
If you turn on reminders, Fog Log schedules local notifications on your device. Local notifications are created and delivered by your phone. They do not involve a server, and nothing about them — not the name of what you take, not the time, not whether you responded — leaves your device.
Fog Log asks for notification permission only when you first set a reminder. If you decline, every other part of the app continues to work.
Fog Log includes a built-in list of prescription, over-the-counter and supplement names so that you don't have to type them from memory. That list is a file inside the app. When you search it, the search runs on your device and nothing you type is sent anywhere.
The lists come from two United States government sources, both free to redistribute: RxTerms, published by the National Library of Medicine, and the Dietary Supplement Label Database, published by the National Institutes of Health Office of Dietary Supplements. Neither organisation is involved in this app, receives anything from it, or knows that you use it.
Fog Log can produce three kinds of file, and each one is created only when you ask for it:
These files are handed to your phone's standard share sheet. What happens next is entirely your choice — you might email one, save it to Files, put it in iCloud Drive, or print it. Once you send a file somewhere, it is governed by the privacy practices of wherever you sent it, not by this policy. If you save a backup to iCloud Drive, for example, it sits in your own Apple account under Apple's terms.
Please think before you send. These files contain your health information.
On the App Store, Fog Log declares that it collects no data. That declaration is accurate and matches the description above.
Fog Log is not directed at children and is not designed for use by them. No information is knowingly gathered from anyone, of any age, because no information is gathered at all.
Fog Log records what you tell it. It does not recommend anything to take, suggest or adjust a dose, warn about interactions between substances, or diagnose or treat any condition. Nothing in the app is medical advice, and it does not replace a conversation with a clinician. If something about your health concerns you, speak to a doctor.
Settings contains a “Delete all my data” control that erases every day you have logged and every item you track from the device. Deleting the app removes the same information. Neither action affects files you have already exported or backed up — those are yours, wherever you put them.
If this policy changes, the updated version will be posted at this address with a new date at the top. Because the app collects nothing, any change is likely to be a clarification rather than a change in practice.
