AlcoLog is operated by Dean Chew, a sole trader domiciled in the United Kingdom. For any privacy-related questions, contact us at privacy@alcolog.app.
AlcoLog is an alcohol consumption tracking app for iOS and Apple Watch. It helps you log drinks, monitor your intake, and understand your drinking habits. AlcoLog is not a medical device and does not provide medical diagnosis, treatment, or advice.
AlcoLog stores all personal and identifiable data on your device only. The following are never transmitted to our servers under any circumstances:
If you choose to opt in to anonymous data sharing, AlcoLog sends stripped-down statistical summaries of your sessions (see "Anonymous usage data" below). These summaries include general timing (day of week, month, hour), cost data with currency, and behavioural patterns, but never exact dates, locations, names, or anything that could identify you.
Location data: AlcoLog uses location services solely for optional geofencing features (such as reminders when arriving at or leaving a saved venue). Location data is processed and stored on your device only. We never receive, transmit, or store your location.
With your permission, AlcoLog writes two data types to Apple Health:
AlcoLog does not read data from Apple Health. HealthKit data is never used for advertising, data mining, or shared with third parties. HealthKit data is governed by Apple's own privacy protections and is not transmitted to our servers.
If you choose to enable "Share Anonymous Data" in Settings, AlcoLog will send anonymised session summaries to our servers. This is off by default and entirely optional.
When you opt in, AlcoLog generates a random identifier (UUID) stored only on your device. This identifier allows us to group your sessions for trend analysis without knowing who you are. It is not linked to your Apple ID, device, or any personal information. If you opt out or delete the app, this identifier is discarded.
Anonymous data is sent via encrypted HTTPS connection to servers hosted by WPX (wpx.net). Data is encrypted in transit and at rest.
AlcoLog offers optional subscriptions (Pro and Premium) via Apple's App Store. All payment processing is handled entirely by Apple. We do not receive, process, or store any payment details, credit card numbers, or billing information.
The AlcoLog iPhone and Apple Watch apps do not use third-party analytics SDKs, advertising networks, crash reporting tools, or social media SDKs. The only external data transmission from the apps is the optional anonymous usage data described above, sent to our own servers.
The AlcoLog website (alcolog.app) uses a small number of standard third-party services:
The AlcoLog website uses cookies for two purposes: essential session state and optional analytics. We do not use advertising, personalisation, social, or cross-site tracking cookies of any kind.
A small amount of functional storage is always active: your cookie consent choice itself (so we don't ask again on every visit) and standard browser storage required for the site to render. These do not require consent under UK GDPR / PECR.
We use Google Analytics 4 to measure aggregate website traffic — pages viewed, approximate region, and referring source. This is only used to understand which parts of the site are useful. We do not combine it with your anonymous in-app identifier, and we do not sell, share, or rent analytics data.
Google Analytics is loaded with Google Consent Mode v2. On page load, all tracking is set to denied. What happens next depends on where you are visiting from:
_ga and _ga_<id>) and begins measuring. If you Reject, Analytics stays in a consent-denied state, which means no cookies are set and no identifiable data is collected. We decide whether the banner is legally required from your browser's reported timezone (read locally via Intl.DateTimeFormat()). Your IP address is not sent to any third party for this check; nothing leaves your device.You can change your cookie choice at any time by clicking Cookie Settings in the site footer. This re-opens the banner so you can accept or reject again, regardless of where you are visiting from. You can also clear all AlcoLog cookies directly from your browser settings.
Our contact form uses Google reCAPTCHA v3 to prevent spam. reCAPTCHA sets a small number of cookies solely for bot detection; it does not fire without you interacting with the contact form. Submitting the contact form implies acceptance of Google's Privacy Policy and Terms.
When you use the barcode scanner to look up a product, the numeric barcode is sent to public product databases to retrieve the product name, alcohol percentage, and calorie information. We do not send any identifier that could link the scan to you.
Depending on your subscription, the following databases are queried:
Our server caches successful lookups for up to 30 days to reduce repeated queries to FatSecret. The cache contains only the barcode and the returned product information. It does not contain any user identifier, IP address, or timestamp linked to a specific user.
Each provider has its own privacy policy. The most relevant ones:
When you use the camera icon on the Add Drink form to identify a drink from a photo, the photo is analysed entirely on your device using Apple's Vision framework. We do not upload the photo to our servers, do not transmit it to any third party, and do not retain a copy on our infrastructure. The photo remains in your camera roll exactly as it would for any other photo you take or choose. Only the resulting drink-type and size guesses are surfaced to the app for you to confirm before logging.
When you submit the contact form on our website, we receive the name, email address, subject, and message you provide. The submission is routed by enquiry type to the appropriate inbox (for example support, feedback, press, privacy, or legal).
For bug reports only, you may optionally attach screenshots or a short screen recording (images and video files). These attachments are sanitised on our server, then passed directly into the outgoing email. They are not stored separately on our web server.
We retain contact correspondence only as long as necessary to respond to and resolve your enquiry, plus a short period for reference and audit. Contact data is not merged with your anonymous in-app data except where specifically required to action a data rights request, as described below.
AlcoLog is not intended for use by anyone under the age of 18. We do not knowingly collect data from minors.
Under UK GDPR and applicable data protection laws, you have the right to:
Because the anonymous data we collect cannot identify you, we will ask you to provide your anonymous identifier (found in Settings > Data & Privacy in the app) to locate your data for access, export, correction, or deletion requests.
To action a data rights request, we need to temporarily pair the email address and name you contact us from with your anonymous identifier. This pairing is required by data protection law so we can verify the request and locate the correct data.
We use industry-standard security measures to protect your data, including:
We may update this policy from time to time. Material changes will be communicated via an in-app notice. The "Last updated" date at the top will always reflect the current version.
