Privacy Policy

Privacy Policy for Caffemeter, a local-first caffeine forecasting and tracking app.

Effective date: May 31, 2026

1. Overview

Caffemeter helps you estimate and plan caffeine intake from coffee, tea, and similar drinks. It lets you create drink cards, log real or planned caffeine, view estimated caffeine over time, adjust profile settings, and export or import your own backup file.

Caffemeter is designed as a local-first app. The app stores your records on your device. The current app does not require an account, does not use a developer-operated cloud database, and does not include advertising or tracking SDKs.

2. Information We Collect

Caffemeter stores information locally on your device so the app can work. The current app code does not show Caffemeter sending user-entered app data to the developer or to a developer-operated server.

Account Information

Caffemeter does not currently require an account.

App Usage Information

The app stores local records when you use app features, such as caffeine sessions, drink cards, planned drinks, profile settings, timestamps, and time zones.

User-Generated Content

Caffemeter stores caffeine-related records that you create, including drink choices, quantities, start and finish times, planned drinks, and profile settings.

Device And Diagnostics Information

The app records time zone identifiers with local records so forecasts and exports can show times correctly. Apple may separately provide crash, diagnostic, TestFlight, or App Store Connect information according to Apple settings and agreements.

Analytics Information

Caffemeter does not currently include third-party analytics or custom analytics code.

Payment/Subscription Information

Caffemeter does not currently include in-app purchase, subscription, RevenueCat, Stripe, or StoreKit billing code.

AI-Related Information

Caffemeter does not currently include runtime AI features. The app does not currently send your prompts, records, files, or images to an AI provider.

Optional Permissions

Caffemeter uses the system file importer for user-selected JSON import and the system share sheet for user-initiated exports. The current app does not request camera, microphone, location, contacts, calendar, HealthKit, motion, Bluetooth, push notification, or Photos access.

Sensitive Or Health-Adjacent Information

Caffemeter can store caffeine intake, planned caffeine, bedtime settings, body weight, and time-based profile information. These can be personal and health-adjacent.

3. Information You Provide Directly

You may enter or create:

  • Caffeine drink type, coffee bean type, unit, quantity, steep number, estimated caffeine amount, and start/finish times.
  • Planned or hypothetical caffeine drinks.
  • Saved drink cards.
  • Bedtime settings, weekend bedtime settings, temporary bedtime overrides, default caffeine drink type, tea extraction settings, body weight, and preferred weight unit.
  • Backup files that you choose to import.

4. Information Collected Automatically

The app automatically stores timestamps and time zone identifiers with records you create or edit. This is used for forecasts, history, migration, and exports.

Caffemeter does not currently include code that automatically sends analytics events, advertising identifiers, tracking identifiers, device identifiers, or user-entered records to the developer.

5. Information From Third Parties

Caffemeter does not currently use third-party sign-in providers, payment providers, analytics providers, AI providers, or cloud database providers.

Apple may provide platform services such as App Store distribution, TestFlight, app review, crash diagnostics, and App Store Connect reporting. If you choose to share an export file through Files, Mail, Messages, a cloud drive, or another app, that destination may process the exported file under its own privacy practices.

6. How We Use Information

We use information stored in the app to:

  • Operate Caffemeter's caffeine forecasting, drink cards, history, profile, export, and import features.
  • Save your preferences and records locally on your device.
  • Estimate caffeine remaining over time using the app's local calculation model.
  • Display timestamps and time zones correctly.
  • Let you export or import a backup file that you control.
  • Debug local data loading problems, including preserving unreadable JSON files locally for recovery.

Caffemeter does not currently use your app records for account authentication, cloud sync, AI-powered features, subscriptions, ads, tracking, or developer-operated analytics.

7. AI Features And User Content

Caffemeter does not currently include runtime AI features. The app does not currently send prompts, uploaded images, caffeine records, profile records, backup files, or other user content to OpenAI, Anthropic, Google Gemini, Apple Intelligence, a local model, or a custom model endpoint.

Because no runtime AI provider is integrated, the app does not currently use your app data for AI model training.

8. How We Share Information

Caffemeter does not currently send user-entered app records to the developer, a developer server, analytics providers, advertising providers, cloud databases, or AI providers.

Information can leave the app in these situations:

  • You choose to export or share a backup file through the system share sheet.
  • You choose a file from another location to import.
  • Apple processes platform-level data for App Store, TestFlight, app review, crash diagnostics, or device backup services.
  • We may disclose information if required by law or to protect safety, rights, or the integrity of the service.
  • If the app or business is transferred, relevant business records may transfer.

9. Data Retention

Local app records remain on your device until you delete the record, change the setting, delete the app's data, uninstall the app, or import/replace data through app features.

Export files are written to the app's Documents directory before the share sheet opens. You are responsible for the copy you share or store outside the app.

Unreadable local JSON files may be copied beside the original file with a .corrupt- timestamp suffix so the app can preserve data that could not be loaded.

No cloud account data, cloud user content, custom analytics logs, custom crash logs, payment records, or AI logs are currently created by the app.

10. Deletion, Export, And User Controls

Caffemeter supports user-initiated Caffemeter JSON backup export and import. It also supports deleting or archiving several record types in the app UI, such as caffeine sessions, planned drinks, and drink cards.

The app does not currently have accounts, so there is no account deletion flow. The app does not currently include custom analytics, so there is no in-app analytics opt-out.

You can control file sharing by choosing whether to export a backup and where to send it. You can control device-level permissions and backups in iOS settings where applicable.

11. Local-Only Data

The current Caffemeter records are stored locally in JSON files in the app's Documents directory. These include caffeine sessions, drink cards, planned drinks, and profile settings.

Caffemeter does not currently use Firebase, CloudKit, a custom backend, or other app cloud storage.

12. Security

Caffemeter relies on the operating system's app sandbox and local file storage. The app writes JSON files atomically, validates imported Caffemeter backup schema names and versions, uses security-scoped access for user-selected import files, and neutralizes spreadsheet formula prefixes in CSV/TSV export rendering.

No custom encryption, server-side access control, Firebase rules, backend security rules, or cloud storage rules are currently used by the app.

13. International Data Transfers

Caffemeter does not currently transfer user records to a developer-operated cloud service. Apple and any user-selected export destination may process information in different countries according to their own practices.

14. Children's Privacy

Caffemeter is intended for adults who choose to consume caffeine and want to estimate or plan their intake. It is not intended for children under 13, and it does not recommend that anyone begin consuming caffeine.

15. US State Privacy Rights

Depending on where users live, they may have rights to know, access, correct, delete, or receive a copy of personal information, and to opt out of certain sale, sharing, targeted advertising, or profiling uses.

Caffemeter does not currently include advertising, tracking, sale, or cross-context behavioral advertising code. The app stores caffeine, bedtime, body weight, and related records locally on your device.

16. EEA/UK Privacy Rights

If EEA or UK privacy law applies, users may have rights to access, correct, delete, restrict, or receive a copy of their personal data, object to some processing, withdraw consent where processing is based on consent, and complain to a data protection authority.

Most Caffemeter app records are stored locally on the user's device and are not currently sent to the developer by the app.

17. Changes To This Policy

We may update this policy when the app changes or when legal, business, or operational practices change. The effective date at the top shows when this version applies.
