Terms of Use – Contaxo for iPhone, iPad and Mac

Effective date: November 7, 2026
Last updated: November 7, 2026

These Terms of Use (“Terms”) govern your use of the Import & Export Contacts Excel (Contacts Excel) app for iPhone, iPad and Mac, including its widgets, Shortcuts actions, backup reminders and the Transfer to New Phone feature (together, the “App”), provided by ONNEX YAZILIM ANONİM ŞİRKETİ (“ONNEX”, “we”, “us”, “our”).

By downloading or using the App, you agree to these Terms. If you do not agree, please do not use the App. These Terms are our end user license agreement for the App.

1. The App

The App lets you export the contacts on your device to Excel, CSV, Word, PDF and vCard files, import contacts from such files, back up and restore your contacts, find and merge duplicate contacts, and move your contacts to a new iPhone or Android phone with a QR code.

You do not need an account to use the App.

2. License

We grant you a personal, non-exclusive, non-transferable, revocable license to use the App on Apple-branded devices that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, including Family Sharing where it is offered. All rights not expressly granted are reserved by ONNEX.

3. Your Contacts and Files

You keep all rights to your contacts and the files you create or import (“Your Content”). We do not claim ownership of Your Content.
How the App handles data is explained in our Privacy Policy – Contacts Excel (iPhone, iPad & Mac).
You are responsible for the contacts you import, export, transfer and share, and you must have the right to use and share them. When you share an exported file, you are responsible for choosing who receives it.
Importing, merging, deleting, restoring and saving transferred contacts change the contacts on your device. The App saves an undo snapshot before merges and deletes, but please review changes before you confirm them and keep your own backups of important contacts.

4. Transfer to New Phone

Transfer to New Phone sends your contacts from one device to another through our encrypted relay, as described in our Privacy Policy – Contacts Excel (iPhone, iPad & Mac). It needs an internet connection on both phones, and the App must stay open on the old phone until the transfer is approved and sent.
Each QR code and link works for 30 minutes and for one device only. Show the QR code or send the link only to yourself or someone you trust, and always check that the 6-digit code on both phones matches before you approve. Do not approve a connection you did not start.
Viewing the received contacts is free. Saving them to the new phone requires Contacts Excel Pro. Contacts that are already on the new phone are not added twice.
The relay is provided “as available”. We may limit, change or stop it, for example to prevent abuse or if a size limit is reached. Your contacts on the old phone are not changed by a transfer.

5. Free Features, Pro and Limits

Some features are free and some require Contacts Excel Pro. The App shows which features are included before you buy.
Free use has limits, for example on the number of contacts you can export or import at once, or on backups you can share.
Features, limits and prices may vary by region and device and may change over time. Changes will not reduce what you have already paid for during your current subscription period.

6. Subscriptions, Free Trials and Purchases

Subscriptions

Pro is available as an auto-renewing subscription (for example monthly or yearly) and, where offered, as a one-time lifetime purchase.
Payment is charged to your Apple Account when you confirm the purchase.
A subscription renews automatically for the same period at the price shown to you unless you turn off auto-renew at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the current period.
You can manage or cancel your subscription at any time in your Apple Account settings (on iPhone or iPad: Settings › your name › Subscriptions; on Mac: App Store › your name › Account Settings › Subscriptions). Cancelling stops future renewals; you keep Pro until the end of the period you have paid for. Deleting the App does not cancel a subscription.

Free trials

Some plans include a free trial. The length of the trial and the price that applies after it are shown before you start.
If you do not cancel at least 24 hours before the trial ends, the subscription starts and you are charged. Any unused part of a free trial ends when you buy a subscription.

Lifetime purchase

A lifetime purchase is a one-time payment that unlocks Pro for the Apple Account used to buy it, without renewals.

Prices, restore and refunds

Prices are shown in the App in your local currency before you buy and may include taxes.
You can restore previous purchases from the App with the same Apple Account.
All payments are processed by Apple. Refund requests are handled by Apple under its policies at reportaproblem.apple.com. We do not receive or store your payment details.

7. Acceptable Use

You agree not to:

use the App for any unlawful purpose or in breach of these Terms
import, export, transfer or share contact data you do not have the right to use, or use the App to send spam
interfere with, overload or bypass the App’s limits, security, transfer relay or purchase systems
copy, modify, reverse engineer or resell the App, except where the law allows it

8. Apple and Third Parties

These Terms are between you and ONNEX only, not Apple. ONNEX, not Apple, is solely responsible for the App and its content.
ONNEX is solely responsible for providing maintenance and support for the App. Apple has no obligation to provide any maintenance or support for the App.
If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App (if any) to you. To the maximum extent permitted by law, Apple has no other warranty obligation for the App.
ONNEX, not Apple, is responsible for addressing any claims by you or a third party relating to the App or your use of it, including product liability claims, claims that the App fails to meet any legal or regulatory requirement, and claims under consumer protection, privacy or similar laws.
If a third party claims that the App or your use of it infringes their intellectual property rights, ONNEX, not Apple, is solely responsible for the investigation, defense, settlement and discharge of that claim.
You confirm that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
You must comply with applicable third-party terms when using the App, for example the terms of your mobile carrier or internet provider. When you share or save a file through another app or service (for example Mail, WhatsApp or Google Drive), that app’s own terms apply.
Apple and its subsidiaries are third-party beneficiaries of these Terms. Once you accept these Terms, Apple has the right (and is deemed to have accepted the right) to enforce them against you as a third-party beneficiary.

Microsoft Excel and Microsoft Word are trademarks of Microsoft Corporation. The App is not affiliated with, endorsed by or sponsored by Microsoft. iPhone, iPad, Mac and iCloud are trademarks of Apple Inc.

9. Disclaimer

The App is provided “as is” and “as available”. To the extent permitted by law, we do not promise that the App or the transfer relay will always be available, error-free or compatible with every device, contacts account or file, or that every field will be converted or transferred exactly in every format.

Nothing in these Terms limits any rights you have under the consumer protection laws of your country that cannot be waived by contract.

10. Limitation of Liability

To the maximum extent permitted by law, ONNEX is not liable for any indirect, incidental, special or consequential damages, or for loss of contacts, data or content, arising from your use of the App. Our total liability for any claim relating to the App is limited to the amount you paid for Pro in the 12 months before the claim.

These limits do not apply where the law does not allow them, including liability for intent or gross negligence.

11. Ending Use

You can stop using the App at any time by deleting it. Deleting the App does not cancel a subscription; please cancel it in your Apple Account settings.

We may suspend or end your access to Pro features or to Transfer to New Phone if you seriously or repeatedly breach these Terms, or if we are required to by law.

12. Changes to These Terms

We may update these Terms from time to time. The latest version will always be available on this page, with the “Last updated” date shown at the top. If a change materially affects you, we will let you know in the App. If you keep using the App after a change takes effect, the updated Terms apply.

13. Governing Law

These Terms are governed by the laws of the Republic of Türkiye. The courts and enforcement offices of Eskişehir, Türkiye have jurisdiction, without affecting any mandatory right you have to bring a claim before the courts or consumer authorities where you live.
