Privacy Policy

Snap to Calendar · Effective July 28, 2026

Snap to Calendar is published by Acorn Labs LLC and is built to know as little about you as possible. There are no accounts, no sign-ins, and no user database. We never sell your data and we never use your photos to train AI models.

Photos you scan

• When you snap or choose a photo, it is resized and re-encoded on your device, then sent over an encrypted connection (HTTPS) to our processing service, which uses an AI model to read the events on it.
• Because the image is re-encoded on your device before it is sent, the uploaded copy does not carry the original file's embedded metadata, including GPS location (EXIF).
• Photos are processed transiently to produce the list of events and are not stored on our servers — not by us and not by our AI provider for training.
• The events the AI reads are shown to you for review and are saved only on your device and into your own Apple Calendar — never on our servers.

Saved scans kept on your device

• When you save events from a photo, the app keeps a copy of that photo on your device only, in the app's private storage, so you can look back at the original schedule later. Each saved calendar event links back to it.
• These copies are never uploaded to us and are not readable by other apps.
• They are kept until you delete them — tap "See all" on the home screen, then the ✕ on any scan, or use "Delete from this phone" while viewing one. Deleting the app removes all of them.
• Deleting a saved scan removes only the photo. Calendar events you already saved are not touched.

Your calendar

• The app adds only the events you approve, to the calendar you choose. It never reads, changes, or shares events it didn't create.

What we collect

• Anonymous per-device usage counts (a random device identifier and a number of scans per day) used solely to enforce the free tier, control costs, and prevent abuse. This identifier is generated by the app, is not your Apple ID, your name, or your device's advertising identifier, and is not linked to your identity.
• Anonymous product-usage events (from version 1.2 onward), sent to PostHog so we can tell whether the app is actually working: that the app was installed, updated, opened, or put in the background; that a scan started, finished, or failed and how many events it found; how many were saved; whether the app flagged a page as possibly incomplete; when the upgrade screen was shown; when an upgrade was bought or a previous purchase restored; and when the scan history was opened. These are counts only. We never send your photos, event titles, locations, notes, links, or any text read from a page — the app is built so that only numbers can be sent, and it strips anything else (including text the analytics library itself tries to attach) before it leaves the device. Like the website analytics below, these events include an approximate country derived from your IP address — never GPS or precise location.
• Nothing else. No profiles, no advertising, no location tracking beyond the approximate country above, no data sold or shared with data brokers.

Service providers we use

• Supabase — hosts the processing function your photo is sent to.
• Anthropic — provides the AI model that reads the events from the photo. Images sent through our service are not used to train their models.
• RevenueCat — validates App Store purchases. It receives an anonymous device identifier, never your name or Apple ID.
• Sentry — receives anonymous crash and error diagnostics.
• PostHog — provides the website analytics described below. It does not receive your photos or your calendar events.
• These providers process data on our behalf and are not permitted to use it for their own purposes. Data may be processed in the United States; where required, appropriate transfer safeguards apply.

This website

• We measure traffic on snaptocalendar.app using PostHog, so we can see which pages people find useful and whether they go on to the App Store. We record the page visited, the referring site, and approximate country, plus a click when someone follows a link to the App Store.
• This is configured to run without cookies and without session recording. We do not build advertising profiles, and we do not track you across other websites.
• Website analytics are entirely separate from the app: PostHog never receives your photos, your scans, or your calendar events.
• To opt out entirely, enable "Do Not Track" or a content blocker in your browser, or simply do not visit the site — none of the app's functionality depends on it.

Purchases

• Subscriptions are sold and processed by Apple. We never see or receive your payment details.

Diagnostics

• The app may send anonymous crash reports and error diagnostics so we can fix problems. These contain technical data only — never your photos, and never your calendar contents.

How long we keep things

• Photos on our servers: not retained at all — the image is discarded once the events are returned to your device.
• Saved scans on your device: kept until you delete them, or until you delete the app.
• Anonymous usage counts: retained only as long as needed to enforce monthly limits and detect abuse, then deleted or aggregated.
• Crash diagnostics: retained on a rolling basis (typically up to 90 days) and then deleted.

Children

• The app is rated 4+ but is designed for general audiences, is not directed at children under 13, and does not knowingly collect personal information from children. Because we collect no accounts or personal details, we hold no children's personal data.

Your rights

• Depending on where you live (for example, under the GDPR in the EU/UK or the CCPA/CPRA in California), you may have rights to access, correct, delete, or port your personal data, and to object to or restrict its processing. Because we do not maintain accounts and hold no information that identifies you, we usually have no personal data to look up. Deleting the app removes the data stored on your device.
• We do not sell or share personal information as those terms are defined under California law.

Changes

• If this policy changes, the effective date above will change. Material changes will be highlighted in the app or on this page.
