Control interest-based advertising on apps on your mobile device. AppChoices gives you transparency with participating companies, and lets you limit their collection of cross-app data for interest-based ads. Brought to you by the Digital Advertising Alliance, and backed up by the DAA’s independent accountability program, AppChoices lets you opt out from interest-based advertising with a particular company, or “Choose All Companies” with one simple click. Did you know that some of the ads you receive in apps are customized based on predictions about your interests generated from your app usage? This is called interest-based advertising (IBA). AppChoices gives you choices about whether you receive this type of advertising that is based on cross-app data collected over time across different apps and devices. To opt out your device ID out of IBA from a particular company, simply navigate to Device ID-Based Choice tool and set the switch next to the company’s logo from “”ON” to “OFF”. AppChoices lets you decide which, if any, participating companies deliver interest-based advertising to your device. Using the new Token ID-Based Choice (beta) tool, you can opt out or revoke having your data collected or used for IBA linked to the email address you provide. When it comes to ads in your apps based on your interests, it’s your choice. AppChoices también está disponible en español. Solo establece la configuración al idioma español. You may still receive other types of advertising in your apps from participating DAA companies, and these companies (and other apps) may still collect information for other purposes consistent with the DAA Principles. You can learn more about these Principles and the DAA’s enforcement and accountability program by visiting www.aboutads.info/enforcement. v2.2.0

Build A Case helps you keep a clear, organized record when you are dealing with a landlord, an employer, a government agency, an insurer, or any party you need to document. When you finally file a complaint, escalate to a regulator, or talk to an attorney, you usually arrive with scattered notes, screenshots buried in Photos, and half-remembered dates. Build A Case gives you one place to put all of it. WHAT YOU CAN DO • Log every interaction — phone call, email, in-person, web form, or letter — with the date, who you spoke to, and what was said. • Attach evidence — photos, video, audio, screenshots, and documents — straight from your camera or library. • Mark up a photo and save the annotated copy alongside the untouched original. • See your whole history on a single timeline, so nothing falls through the cracks. • Export a clean PDF case file you can hand to an agency, a regulator, or a lawyer. BUILT FOR TRUST • Every file is fingerprinted with a SHA-256 hash and timestamped, so you can show it has not been altered since you saved it. • Everything stays on your device. There is no account to create and no server we control. Optional iCloud Sync (off by default) keeps your files in your own private iCloud. • Lock the app with Face ID so your records stay private. WHERE TO FILE Build A Case includes built-in reference information for U.S. federal and state agencies and the kinds of issues people commonly document — housing, employment, consumer and financial, insurance, civil rights, education, and more — so you have a starting point for where a complaint may go. PRIVACY FIRST We collect no data, run no analytics, and show no ads. Your case files are yours. Build A Case is a documentation and organization tool. It is not a law firm and does not provide legal advice. It is not a substitute for a licensed attorney or other professional. If you are in crisis, the app links to 988 and other support resources. Free to use for documentation. A one-time in-app purchase unlocks unlimited PDF exports after a 30-day free trial.
