AlcoLog can write your drink data to Apple Health after each session ends. This tutorial walks through enabling the sync, what exactly gets written, how to confirm it’s working, and how the boundary works. The sync is one-way: AlcoLog can write to Health but cannot read from it. Your other Health data stays private to the Health app.
# Step 1. Open the Apple Health section
Tap the Settings tab and scroll near the bottom to the Apple Health section. The first time you visit, the Sync with Health app toggle is off and a What we write to Apple Health disclosure is collapsed below.
Apple Health sync is a Pro feature. Free users see the toggle locked with a Pro badge. Tap the badge for the in-app upgrade prompt.

# Step 2. Turn the toggle on
Tap the Sync with Health app toggle. iOS shows its native Apple Health permission sheet asking which categories AlcoLog can access. Two are requested:
- Number of Alcoholic Beverages (write only)
- Dietary Energy (write only)
Tap Turn On All at the top, or enable each individually. There is no read access requested. AlcoLog cannot pull anything back; only writes go through.
After granting permission, the toggle stays on. From now on, every session you finish will write its totals to Health when you tap End Session.
# Step 3. Read the disclosure
Back on the AlcoLog Apple Health section, expand the What we write to Apple Health disclosure. It explains exactly what flows across:
- Alcoholic Beverages: every drink you log with ABV ≥0.5% counts as one standard drink under Apple’s Nutrition category. Water and 0% drinks are excluded.
- Calories from Alcohol: the calorie count for each drink, written to Apple’s dietary energy field.
- What we don’t write: alcohol-free drinks, medication doses, location, drink brand, drink type, or any AlcoScore data.
The disclosure also has a red What we never collect sub-card making the read boundary explicit: Nothing flows back from Health into the app; the sync is purely outbound.
# Step 4. Verify it’s working
Open Apple’s Health app on your iPhone. Tap Browse at the bottom, then tap Nutrition. Scroll to Number of Alcoholic Beverages and Dietary Energy.
After you finish your next session in AlcoLog, refresh either of those screens. Each drink in your session shows up as a separate entry, time-stamped to when you logged it. The source for each entry reads AlcoLog.
If nothing appears: check that the toggle in AlcoLog is still on, and that the iOS Health permission still shows write access for both categories. Permissions occasionally drop after iOS updates and need re-granting.
# Step 5. The boundary
Apple Health sync is one-way and that’s deliberate. AlcoLog has no need for your heart rate, sleep stages, or workout data; including it wouldn’t change what AlcoScore measures, and it’d give us a much larger privacy surface than we want.
If you want to delete your AlcoLog drink entries from Health, you can do that inside the Health app. Tap any entry, swipe left, delete. The deletion does not propagate back to AlcoLog (the writes are independent), so the same entry will stay in your AlcoLog session history. To match the two, also delete the drink or session in AlcoLog (see editing or deleting).
That’s the whole sync. One toggle, write-only access, two categories.
