iOS 26.5 RC App Sideloading Brazil: Rules, Limits Explained

Apple's April compliance deadline with Brazil's antitrust authority CADE has arrived, and iOS 26.5 RC is the software release that fits the window. Brazilian iPhone users are set to gain access to alternative app marketplaces and external payment options. What they are not getting is the ability to download apps directly from a developer's website and that distinction matters more than most coverage of iOS 26.5 RC app sideloading in Brazil has acknowledged.

The CADE settlement, analyzed by Truth on the Market earlier this year, does not require web-based app installation what Apple calls "Web Distribution" in the EU. That omission is the difference between a narrow competitive opening and a full structural change to how iOS works.

One caveat upfront: no source has confirmed what Brazil-specific functionality iOS 26.5 RC actually contains. Apple has not published release notes on the matter, and the full CADE settlement text remains private. What is established is the compliance timeline. Apple had 105 days from the settlement date to implement the required changes, pointing to an April deadline, per heise's reporting last December. iOS 26.5 RC arriving now fits that window. The connection is a reasonable inference, not a confirmed product finding.

Does iOS 26.5 RC Brazil actually bring app sideloading?

That depends on how you define the term, and most headlines have been sloppy about it.

Alternative app marketplaces: yes. Apple must permit third-party stores to distribute iOS apps in Brazil, according to Truth on the Market's analysis. For users, the experience would resemble the EU model: install a separate marketplace app, then browse and download apps from a competing storefront. Apple's own EU developer documentation confirms users access alternative marketplaces this way.

External payments and anti-steering removal: yes. Developers will be permitted to use third-party payment processors inside their apps and to direct users to external websites to complete purchases, per the same analysis. Previously, CADE ruled Apple's anti-steering restrictions on Brazilian developers illegal following a 2023 complaint by MercadoLibre, according to PocketGamer. This payment change could reach users before any new marketplace launches some apps may begin offering alternative checkout flows without needing a competing storefront to exist first.

Web distribution: no. The settlement does not require Apple to support downloading apps directly from a developer's website. That is the capability closest to sideloading in the traditional sense, and Brazil's framework leaves it out entirely, per Truth on the Market.

The practical picture by audience:

• Everyday iPhone users in Brazil: May see new checkout options inside apps; alternative marketplaces could appear, but only if developers choose to build them.
• Developers: Can offer external payment links and use competing processors, a direct revenue change that does not require any new storefront to exist.
• Marketplace operators: The regulatory door is open, but Apple's notarization requirement and the fee structure discussed below shape how attractive building a competing storefront actually is.

How Brazil got here: two years of rulings, appeals, and a negotiated settlement

The changes tied to Apple's April compliance deadline did not emerge from a single decision. They are the product of a process that ran through orders, appeals, reversals, and eventually a negotiated settlement and the shift from court orders to settlement matters, because it explains why the final framework is narrower than earlier coverage suggested.

The dispute began with a 2023 MercadoLibre complaint to CADE. In November 2024, CADE ruled that Apple could no longer prevent developers from distributing apps or selling content outside the App Store in Brazil, according to 9to5Mac. Apple appealed, and a Federal Civil Court temporarily froze the order.

The injunction did not survive. A Brazilian federal high court reinstated the requirement in March 2025, setting a 90-day implementation deadline. The court pointed directly to the EU experience, noting Apple had already met comparable obligations elsewhere "without demonstrating a significant impact or irreparable damage to its business model," as reported by 9to5Mac. The order was then appealed again, reversed, and reinstated once more procedural back-and-forth that PocketGamer tracked through May 2025.

By late 2025, the dispute moved from litigation to a negotiated compliance framework. That shift is significant: the court orders from earlier in the year had been described using the word "sideloading" broadly, but the settlement Apple ultimately signed is more precise and more limited. The CADE agreement gave Apple 105 days to implement changes and tied non-compliance to penalties of up to 25 million euros, per heise. The obligations run for three years.

Apple's public position throughout was consistent: the changes would "compromise the privacy and security" of iOS users, according to heise. The court dismissed that argument by pointing to the EU precedent. Apple retains the right under the settlement to require notarization for any app distributed through alternative marketplaces, preserving a review step for every iOS app regardless of which storefront carries it.

Opening the platform without leaving the transaction

Alternative marketplaces in Brazil do not mean Apple exits the revenue picture. The fee structure embedded in the CADE agreement ensures Apple collects across most distribution paths.

Apps distributed through alternative marketplaces will be subject to a 5% Core Technology Fee on net sales, according to Truth on the Market. Developers routing purchases through external websites rather than Apple's payment infrastructure face a 15% commission on transactions initiated on iOS, per the same analysis. Standard App Store commissions remain at 30%, broken down as 25% for distribution and 5% for in-app purchases. Truth on the Market notes these fees apply even outside Apple's storefront, meaning the economics of building a competing marketplace are less attractive than the regulatory opening might suggest.

The notarization requirement reinforces that position. Apple has framed it as consumer protection, screening apps for security and integrity before they reach users regardless of which store distributed them. The practical effect is a retained review step over every iOS app. Whether that is a legitimate safeguard or a preserved gatekeeping mechanism is a question regulators in other jurisdictions will have to answer for themselves.

What to watch next

iOS 26.5 RC is the start of an obligation that runs for roughly three years, meaning Apple will need to maintain this framework across multiple iOS releases.

The broader question is whether Brazil's model influences other markets. The EU's Digital Markets Act produced wider requirements including web distribution backed by statute. Brazil's framework rests on a negotiated settlement and on CADE's definition of the relevant market as "the distribution of apps on iOS devices," a single-brand market definition. Truth on the Market notes that framing did not hold in US courts: in Epic v. Apple, the district court rejected a comparable "market of one" theory and defined the relevant market as "digital mobile gaming transactions." That limits how directly exportable Brazil's approach is, but it does not stop other regulators from watching.

Three things are worth tracking in the weeks ahead: Apple's release notes for iOS 26.5, any public release of the full CADE settlement text, and whether any marketplace operator announces plans to launch in Brazil. The regulatory change is documented. Whether it produces actual competition depends on those answers.
