Terms of use

Effective 16 October 2026

Shift Calendar - Pay Diary is provided by Julian Sainz Martinez. Your use of the app is governed by Apple’s Standard Licensed Application End User License Agreement and the applicable App Store terms. This page explains the app’s features and purchase model; it does not replace your statutory consumer rights or Apple’s standard licence.

Annual access, free trial and lifetime access

From app version 1.1, new customers choose an auto-renewing annual subscription or a separate, non-consumable lifetime purchase. Active trial, subscription or lifetime access is required for normal calendar, pay, widget and reminder features. The App Store displays the applicable regional price and purchase terms before you confirm.

Eligible Apple Accounts can start a 7-day free introductory trial on the annual subscription. Apple charges the annual price after the trial unless you cancel at least 24 hours before it ends. The annual subscription renews automatically until cancelled. Manage or cancel it in your Apple subscription settings. Cancelling preserves access until the current trial or paid period expires; it does not provide an automatic refund.

Lifetime access is one separately confirmed payment and has no recurring charge. It does not automatically purchase itself after a trial. The app does not offer a lifetime purchase while an annual subscription is active; cancel the subscription and wait until access expires before switching. Refunded or revoked lifetime purchases no longer grant permanent access. Lifetime access refers to the app’s unlocked feature entitlement, not a promise of compatibility with all future operating systems or indefinite updates.

Existing customers and expired access

Existing lifetime owners keep their permanent access without buying again. Original 14-day trials retain their original purchase date and full duration, do not renew and do not automatically charge you. Restoring an original trial does not restart it. Existing installations keep viewing, backup, export and deletion, and their original one-time lifetime upgrade option.

For new customers, expired access returns to the purchase screen. Saved records remain on the device. Export, backup and deletion remain available through the recovery screen without payment. Restore purchases using the Apple Account that purchased access; calendar backups do not contain purchase rights.

Pay estimates and work records

The app is a personal planning and record-keeping tool. Gross estimates depend on the shifts, actual work, rates and rules you enter. They do not calculate income tax, deductions, net salary, statutory leave accrual or every employment agreement. Compare gross with gross and check your official work records and pay statement. A displayed difference is not a determination of underpayment or entitlement. Built-in public holiday lists are provided for convenience, cover national holidays and may not match your region, employer or contract; check and adjust them before relying on holiday pay estimates.

Your local data

You control the information you enter and the files you share. Keep regular backups in a location you control. A purchase does not back up your calendar, and restoring a purchase does not restore work records. The developer cannot retrieve your lost local data or recover a forgotten backup password. Read the privacy policy for details about optional permissions, exports and providers.

Payslip documents

You may save readable, unlocked PDF copies up to 10 MB each for personal reference and manual comparison. The app does not interpret a payslip or verify its accuracy. Saved PDFs are included in full backups; backups containing PDFs require app build 3 or later. Keep original documents and backups in a location you control.

Reminders and shared schedules

Local reminders depend on device settings and iOS delivery and are not guaranteed wake-up alarms. Shift alarms (iOS 26) also depend on your device, its settings and charge. Shared schedule files are snapshots, not live synchronization. Live sharing and iCloud sync (from version 1.1.1) depend on iCloud being available and up to date on each device; a shared schedule shows what the owner last published. Confirm important work arrangements through your employer’s usual process.

Support and purchases

For app support, visit the support page. Payment, billing and refund requests are handled through Apple’s purchase support, including Report a Problem. Eligibility depends on Apple’s terms and applicable law.
