Terms of use

About these terms

These terms cover your use of the DataSplit app and this website. They are deliberately short, because the app is simple to reason about: no accounts, no user content, and nothing stored anywhere but your device.

Accepting the terms

By downloading or using DataSplit you agree to these terms. If you do not agree with them, do not use the app.

What DataSplit does

DataSplit counts internet data on your iPhone and helps you keep the budgets you set. The free version counts, warns, and shows usage on any number of networks. DataSplit Pro adds the enforcement: it can pause data automatically, hold back a safety buffer, slow the connection down, block apps you selected through Screen Time, and pause everything at once with the emergency stop. You set the rules, and you can change or remove them at any time in the app. The exact set of features in the free version and in Pro can change with updates.

Counting accuracy

DataSplit measures traffic on the device, which is very close to what your carrier measures, but not identical. Carrier meters add radio overhead and rounding, Personal Hotspot traffic can only be estimated, some system traffic travels outside the counted path, and data used while counting was off is only known to the app if you enter it yourself. The amounts on your provider’s bill are decisive, not the amounts in the app. On plans where going over costs money, use the safety buffer and keep an eye on your provider’s own meter.

No guarantee against charges

DataSplit exists to help you avoid overage charges, but it cannot guarantee that. Counting works only while data counting is on: you can turn it off yourself, starting another app of the same kind turns it off, and iOS itself can end it, and any data used in the meantime flows without being counted or paused. You remain responsible for all charges from your network provider, including data, roaming, and overage fees.

Paused data and connectivity

When a budget runs out, DataSplit pauses internet data until you give it more room. That is the point of the app, but it means the internet on your device can be unavailable or slowed down by rules you set earlier. Do not rely on a budgeted connection in situations where losing connectivity could cause harm. Pausing affects internet data only; regular cellular calls and SMS text messages are not part of the data path the app manages.

One app at a time

iOS allows only one app at a time to manage the connection the way DataSplit does. While data counting is on, another app of that kind cannot run, and starting one turns data counting off.

Name lookups (DNS)

While data counting is on, DataSplit sets your device to use public DNS servers: Cloudflare (1.1.1.1 and 1.0.0.1) and Google (8.8.8.8). It does this so names keep resolving on every network it counts on. Those companies then receive the names your device looks up and the address the lookup comes from, and they handle them under their own privacy terms: see Cloudflare’s public resolver privacy page and Google Public DNS privacy. DataSplit does not read, store or transmit your lookups, and it sends those providers nothing about you. The privacy policy describes this in full.

One practical consequence is worth knowing before you rely on it: on a company, campus, or other private network, addresses that only that network knows may not resolve while data counting is on. Turning data counting off gives your device the DNS servers your network or your own settings provide.

Screen Time app blocking

With Pro, DataSplit can block apps you picked through Screen Time when a budget threshold is crossed. Blocking makes the whole app unavailable, not just its internet data, so pick apps you can do without. You are responsible for that choice, and you can lift the block at any time in DataSplit or by revoking Screen Time access in iOS Settings.

Purchases and subscriptions

DataSplit is free to download and use, and it contains no advertising. DataSplit Pro is unlocked with an in-app purchase: an automatically renewing monthly or annual subscription, or a one time lifetime purchase that supports Family Sharing. Prices and the subscription period are shown in the app and on the App Store before you buy, and payment is charged to your Apple account when you confirm the purchase; we never see your payment details. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and you can manage or cancel them at any time in your App Store account settings. Where a free trial or introductory offer exists, it converts into a paid subscription unless cancelled before it ends, and any unused portion is forfeited when you buy a different plan. The lifetime purchase is a single charge tied to your Apple account and can be restored on any device signed in to it. Refunds are handled by Apple under Apple’s own terms; we cannot issue them ourselves.

Apple’s role

These terms are an agreement between you and the developer, not with Apple. Apple has no obligation to provide maintenance or support for DataSplit and is not responsible for the app, its content, or any claims relating to it, including product liability, legal compliance, and intellectual property claims. Apple and its subsidiaries are third party beneficiaries of these terms and may enforce them against you.

When Pro ends

If a subscription ends or is refunded, the app returns to the free version: counting, budgets, warnings, widgets, and history keep working, the automatic enforcement turns off, and everything you set up stays on your device.

Intellectual property

DataSplit, including its code, design, and name, belongs to its developer. You get a personal, non-transferable license to use the app. Do not copy, resell, or redistribute the app or its assets.

Disclaimer

DataSplit is provided as is. We do not promise that the app will always be available, bug free, or compatible with every device or network. For consumers in the European Union this does not limit your statutory rights: if the app does not do what these terms and the App Store listing say it does, you keep the remedies consumer law gives you.

Limitation of liability

We are not liable for damages arising from your use of DataSplit, except as set out in this section. That includes charges from your network provider, and costs or losses caused by data being paused or slowed down, by apps being blocked, or by counting that differs from your provider’s meter. This limitation does not apply to damage caused by our intent or gross negligence, to death or personal injury, or to any liability the law does not allow us to limit. Where we are liable despite this section, our total liability is limited to what you paid for DataSplit Pro in the twelve months before the event that caused the damage, or to the price of your lifetime purchase if you bought Pro that way.

Changes to the app and these terms

We may update the app and these terms. A change to the terms that does not reduce your rights applies from the moment it is published on this page. For a change that does reduce your rights, or that takes away something you paid for, we give reasonable advance notice in the app or on this page, and you can cancel your subscription before the change takes effect. If we ever discontinue the app, your statutory rights as a consumer are not affected.

Termination

You can stop using DataSplit at any time by deleting the app; that also deletes everything it stored.

Governing law

These terms are governed by the laws of the Netherlands. If the consumer law of the country you live in gives you rights that cannot be waived, those rights are not affected by anything in these terms.

These terms apply to the DataSplit iOS app and to data-split.com, operated by Nicolaas Vertelman.
