Privacy Policy.

Caliq is a calendar and planning app for iPhone, iPad, and Mac that turns notes, screenshots, and invites into calendar events. This Privacy Policy explains what personal data Caliq processes, why, which service providers are involved, how long data is kept, and how you can control or delete it. It covers the Caliq apps, the Caliq account, Caliq's servers on Cloudflare (api.caliq.eu and Caliq's parsing server), and this website.

Last updated: October 30, 2026

1. Privacy at a Glance

• No ads, no tracking, no data sales. Caliq does not show advertising, does not use advertising or analytics SDKs, and does not sell or rent personal data.
• Your calendars are read on your device. Caliq reads and writes your calendars through Apple's calendar framework, only with your permission. Only the details of events created from your notes sync with your Caliq account.
• Signing in is optional on the free plan. You can sign in with Apple, Google, or a one-time email code. You need a Caliq account to buy Pro or Max, and for sync and account backups.
• Google sign-in is limited to your basic profile. Caliq does not access your Gmail, Google Calendar, Google Drive, contacts, or any other Google data.
• You can delete your account. Deleting your account in the app removes your profile, synced data, and backups from Caliq's servers.

2. Who Is Responsible

Caliq is developed and operated by Tridib Banerjee, Germany ("Caliq", "we", "us"), who is the controller of the personal data described in this policy. For privacy questions or requests, email [email protected] or use the contact page.

3. The Caliq Account and Sign-In

a. Install account

When you first open Caliq on iPhone, iPad, or Mac, the app creates an anonymous install account on Caliq's servers. It has a random identifier, a placeholder name and email address that are not yours, and a session record (section 3b). Caliq uses it to apply plan limits and to prevent abuse of free trials. If you later sign in, the install account is merged into your full account. If you never sign in, you can ask for your install account to be deleted by emailing [email protected].

b. Signing in

Signing in is optional on the free plan. You need it to buy Pro or Max, for sync and account backups, and to use your plan on your other devices. Caliq does not use passwords. You can sign in with:

• Sign in with Apple: Caliq receives a stable Apple user identifier, your email address (or an Apple private relay address), and the identity token Apple issues. Caliq does not currently store the name you share with Apple.
• Sign in with Google: see section 4.
• Email code: Caliq emails a six-digit code to the address you enter. The code is valid for 10 minutes.

Sign-ins with Apple, Google, or an email code that use the same verified email address open the same Caliq account.

Each sign-in creates a session that is valid for 90 days and is renewed while you use the app. The session token is stored in your device's Keychain. Caliq's servers store a record of each session with its token, expiry, IP address, and device user agent, to keep sessions secure and detect misuse. Signing out removes the session from your device; the session record on the server stays valid until it expires. After you sign out or delete your account, the app starts a new install account.

4. Google User Data

This section describes how Caliq accesses, uses, stores, and shares data received from Google when you choose Sign in with Google.

a. What Caliq accesses

Caliq requests only the standard Google sign-in scopes openid, email, and profile. From these, Caliq receives your Google account identifier, your name, your email address and whether Google has verified it, and the address of your Google profile picture. Google also issues sign-in tokens for these scopes, which Caliq's sign-in system stores.

Caliq does not request access to Gmail, Google Calendar, Google Drive, Google Contacts, or any other Google API. If you have added a Google calendar to your iPhone, iPad, or Mac, Caliq can see it only through Apple's calendar framework on your device, under the calendar permission you grant to Caliq, and not through any Google API.

b. How Caliq uses it

• To create your Caliq account and sign you in on your devices.
• To show your name and email address on the Account page in the app.
• To open the same account when you sign in with Apple or an email code using the same verified email address.
• To contact you about your account, for example in reply to a support request.

Caliq stores the address of your Google profile picture but does not currently display it. Caliq does not use Google user data for advertising, does not sell it, does not use it to build profiles, and does not use it to train or improve artificial intelligence or machine learning models.

c. How it is stored and protected

Your Google profile data and tokens are stored in Caliq's account database, hosted on Cloudflare in Western Europe. Data is encrypted in transit with TLS and encrypted at rest by Cloudflare. Access is limited to the Caliq operator for running and supporting the service.

d. Sharing

Caliq does not share Google user data with third parties, except with its hosting provider Cloudflare, which stores it on Caliq's behalf, or where required by law.

e. Retention and deletion

Google user data is kept for as long as your Caliq account exists. When you delete your account in the app (section 12), your Google profile data and tokens are deleted from Caliq's servers. You can also remove Caliq's access at any time in your Google Account under Third-party apps and services. This invalidates the Google tokens Caliq holds. It does not sign you out of Caliq, and your next Google sign-in will ask for your consent again.

f. Google API Services User Data Policy

Caliq's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

5. Information Caliq Processes

a. Notes and imports

Caliq stores the notes you write and the text taken from content you import, such as shared text, screenshots, ICS files, and calendar links. Text in images is recognized on your device, and the images themselves are not stored. Caliq adds your notes and plans to Spotlight on your device, so Search and Siri can find and open them.

b. Calendar data

With your permission, Caliq reads and writes events in the calendars on your device to create events, detect conflicts, find availability windows, and power Day Glance, widgets, and timelines. For each event created from a note, Caliq keeps a link with the event title, start and end time, location, calendar name, and a preview of the note. When you delete such an event, Caliq keeps a deletion marker with the event title until your devices have applied it, plus 30 days.

c. Location, weather, and places

If you allow location access while using the app, Caliq uses your location to show local weather and to suggest nearby places when you enter an event location. Caliq also stores the weather places you save (name and coordinates) and looks up the locations of events in your calendars to show the weather there. Weather comes from Apple WeatherKit and place search from Apple MapKit, which receive the coordinates or search text needed for each request. If you choose to open a location in Google Maps, that location is sent to Google.

d. Profile picture

You can add a profile picture to your Caliq account from your photos or by creating one with Image Playground. It is stored with your account.

e. Subscriptions

Purchases are handled by Apple, and Caliq does not receive your payment details. Caliq receives your signed App Store transactions and App Store Server Notifications. It stores selected fields of the transactions and the notifications in full. The notifications include transaction identifiers, product, plan, status, price, currency, storefront country, offer type, family sharing status, auto-renewal status, and purchase, renewal, expiry, and refund dates.

f. Usage records

To apply plan limits, Caliq records each note you log (whether parsed on your device, in Apple Private Cloud Compute, or on Caliq's server), each weather update, and each use of Day Glance. Each record holds the feature and, for weather, the request type, the engine used, the result, duration, quantity, time, time zone, a random device identifier, and when it was received. Usage records do not contain note text, event titles, or coordinates.

g. Device information

For sync and the device limit of paid plans, Caliq stores a random identifier for each device, its type (such as iPhone or iPad), platform, and when it was first and last seen.

h. Security and abuse prevention

• Caliq uses Apple App Attest and your signed App Store transactions to verify that requests come from a genuine copy of the app. Caliq's parsing server stores an integrity record for each install (an App Attest key on iPhone and iPad or a device key on Mac, with its public key, counter, and when it was registered and last seen) and a parsing counter for each subscription. Earlier app versions also kept a counter for some Apple Accounts or devices on the free plan.
• When you use a plan on a device other than the one that bought it, Caliq's account server gives that device a short-lived ticket naming your plan, which Caliq's parsing server checks before server parsing.
• To prevent repeated free trials and refund abuse, Caliq keeps keyed hashes of your App Store transaction identifiers together with trial and refund status.
• When Apple reports a refund or revoked purchase, Caliq records it against the hashed identifiers of your account and purchases, for possible use in limiting future free trials. This happens whether or not Fair refunds is on.

i. Support and website contact form

When you email support or use the contact form, Caliq processes your name, email address, message, and, for the form, the page you sent it from, the referring page, and your browser's user agent. Contact form messages are stored in Caliq's database on Cloudflare and forwarded to Caliq by email.

6. Sync and Backups

Sync is available on every plan once you sign in. Caliq syncs between your devices your notes, the event links described in section 5b, saved weather places, deletion markers, and selected app settings such as theme, filters, weather, and reminder preferences. After a synced record is deleted, a record of the deletion without content is kept for 180 days.

On Pro and Max, Caliq also keeps account backups, up to 10 on Pro and 30 on Max. A backup contains your notes, event links, deletion markers, settings, and saved weather places. Weather forecasts are never backed up or synced. Caliq also stores each backup's date, device, item counts, and app version. Older backups are removed automatically as new ones are made.

Synced data and backups are stored on Cloudflare's network. They are encrypted in transit and at rest by Cloudflare, but not end-to-end encrypted, so Caliq's servers can read them to perform sync.

iCloud. Earlier versions of Caliq on iPhone, iPad, and Mac can sync and back up data through your iCloud account. The current Mac app does not use iCloud. That data is stored by Apple under your iCloud account and Apple's privacy policy, not on Caliq's servers. When you move an older iCloud backup to your Caliq account, the iCloud copy is deleted. The current iPhone and iPad app uses iCloud only to share weather request counts between your devices and to show, restore, or move backups that earlier versions made in iCloud.

7. Note Parsing and Intelligent Features

Caliq finds dates, times, places, and people in your notes in three ways:

• On your device: Apple's on-device Foundation Models and Caliq's own rules. The note text does not leave your device.
• Apple Private Cloud Compute: on supported devices with an internet connection, on every plan, note text may be processed by Apple Intelligence in Apple's Private Cloud Compute, which Apple designs so that data is used only for your request and is not stored or accessible to Apple.
• Server parsing: the note text (up to 4,000 characters), your time zone, and the current time are sent through Caliq's parsing server to a third-party AI provider (currently OpenAI), which returns the events in the note. Server parsing is part of Pro and Max only. Caliq asks for your permission the first time it would send a note this way, and uses it only while Server parsing is on in Settings. The free plan never uses server parsing. Earlier versions of the app parsed up to 15 free plan notes this way when the device could not use Private Cloud Compute.

Notes may also be parsed while you type, to show suggestions before you log them. On Pro and Max, turning Server parsing off stops server parsing. Private Cloud Compute and on-device parsing are still used.

Caliq's parsing server does not store the note text. Its logs record request details such as App Store transaction identifiers and, if parsing fails, an excerpt of the model's result or error. OpenAI processes this data as Caliq's service provider, does not use data sent through its API to train its models, and may keep requests and responses for up to 30 days.

8. Legal Bases

Where the GDPR or similar laws apply, Caliq relies on these legal bases:

• Performance of a contract (Art. 6(1)(b) GDPR): providing the app, your account, sign-in, sync, backups, note parsing, weather and place search, subscriptions, and support.
• Legitimate interests (Art. 6(1)(f) GDPR): securing the service, verifying genuine app requests, preventing trial and refund abuse, applying plan limits, keeping server logs, and fixing errors.
• Consent (Art. 6(1)(a) GDPR): device permissions such as calendar, location, and notifications, and the optional Fair refunds setting (section 9). You can withdraw consent at any time in the app or in your device settings.
• Legal obligation (Art. 6(1)(c) GDPR): keeping records required by tax and commercial law and answering lawful requests.

9. Service Providers and Sharing

Caliq shares personal data only with the providers needed to run the features you use:

• Cloudflare hosts api.caliq.eu, Caliq's parsing server, the account database, sync storage, backups, server logs, and this website, and provides network security and the Turnstile check on the contact form.
• OpenAI processes note text for server parsing (section 7).
• Resend delivers sign-in code emails and forwards contact form messages to Caliq.
• Apple provides Sign in with Apple, App Store purchases and notifications, App Attest, Private Cloud Compute, WeatherKit, MapKit, and iCloud.
• Google provides Sign in with Google (section 4), and Google Maps when you choose to open a location there.

Fair refunds. If you turn on Fair refunds and later ask Apple for a refund, Caliq tells Apple how much of your plan's server parsing you used since the purchase or last renewal (except when it recommends a partial refund of a subscription), whether Caliq recommends declining, a partial refund, or a full refund, and that the plan was delivered and could be tried for free. Without this setting, Caliq sends Apple nothing about your usage. Caliq keeps a record of each refund request, including whether Fair refunds was on, the usage share, and the answer sent.

Caliq may also disclose data if required by law or to protect the rights and safety of its users and the service. Caliq does not sell or share personal data for advertising.

10. International Data Transfers

Caliq's account database is stored in Western Europe. Sync storage, backups, and server logs are on Cloudflare's network and may be stored outside the European Economic Area. OpenAI, Resend, Apple, and Google may process data in the United States or other countries. Where data leaves the European Economic Area, Caliq relies on the EU-U.S. Data Privacy Framework where the provider is certified, or on the European Commission's Standard Contractual Clauses.

11. Data Retention

• Account, profile, synced data, profile picture, and backups: until you delete them or delete your account.
• Install account without sign-in: until you ask for it to be deleted.
• Session records: until you delete your account. Each session is valid for 90 days.
• Sign-in codes: valid for 10 minutes.
• Deletion markers for synced records: 180 days.
• Detailed usage records: 90 days. Daily and monthly totals are kept until you delete your account.
• Subscription records, App Store transactions and notifications, and refund request records: as long as needed for billing, tax, and legal obligations, also after account deletion.
• Trial and refund abuse records: 18 months after the later of the last refund and account deletion.
• Keyed hashes of App Store transaction identifiers: without a fixed end date. They cannot be read back as identifiers, but can be matched against an identifier Caliq sees again.
• Integrity records and parsing counters on the parsing server: without a fixed end date. They are not deleted with your account and contain no name, email address, or note content.
• Server logs, which include account and App Store transaction identifiers: a limited period set by Cloudflare, for security and troubleshooting.
• Recovery copies: deleted data may remain in Cloudflare's database recovery copies for up to 30 days.
• Support emails and contact form messages: as long as needed to handle your request and keep support records.
• Data on your device: until you delete it or remove the app.

12. Deleting Your Account

When you are signed in, you can delete your Caliq account at any time on the Account page in the app with Delete Account. This deletes your profile, sign-in links and tokens, sessions, synced data, backups, profile picture, devices, preferences, and usage records and totals from Caliq's servers. The records listed in section 11 as kept after account deletion remain. Subscription records keep the purchase account token, which equals your former account identifier, or, for purchases made before signing in with earlier app versions, your install account's identifier.

Deleting your account removes the link to your Apple ID from Caliq's servers. To also remove Caliq from your Apple Account, stop using Sign in with Apple for Caliq in your Apple Account settings. To remove Caliq from your Google Account, see section 4e.

Deleting your account does not cancel an App Store subscription; manage that in your Apple account settings. Notes and events stored on your device stay there until you delete them. If you never signed in, or cannot use the app, email [email protected] to request deletion.

13. Security

Caliq protects data with TLS encryption in transit, encryption at rest by its hosting provider, session tokens kept in the device Keychain, App Attest request verification, rate limits, and access restricted to the operator. No system is completely secure, but Caliq works to protect your data and will notify you and the authorities of a breach where the law requires it.

14. Children

Caliq is not directed at children under 13 and does not knowingly collect their personal data. Where local law requires a higher age for consent, a parent or guardian must agree. If you believe a child has given Caliq personal data, contact [email protected] and it will be deleted.

15. Your Rights

Depending on where you live, you have the right to access, correct, delete, restrict, or object to the processing of your personal data, to receive it in a portable format, and to withdraw consent at any time without affecting earlier processing. You can exercise many of these rights directly in the app by editing or deleting content, turning off permissions, or deleting your account. For anything else, email [email protected]. You also have the right to lodge a complaint with a data protection supervisory authority, in particular in your country of residence or in Germany.

16. This Website

This website does not use analytics, advertising, or tracking cookies. Cloudflare, which hosts the site, processes technical data such as your IP address and browser details to deliver pages and protect the site. The contact form uses Cloudflare Turnstile, which receives your IP address to check that the request comes from a person.

17. Changes to This Policy

Caliq may update this Privacy Policy when the app or the law changes. The current version is always on this page with its date.
