Adeux.app's answer

Adeux is designed to be a truly private space for couples. Unlike most messaging or social apps, it focuses only on the relationship between two people. It combines meaningful daily questions, shared memories, private chat, bucket lists, and relationship tools in one place. The goal isn’t just communication — it’s helping couples create moments, reflect together, and strengthen their emotional connection over time.

PrivacyNotes's answer:

PrivacyNotes is the only zero-knowledge encrypted workspace that keeps notes, tasks, journals, files, and a password vault behind one set of on-device keys. Most privacy apps do one of those well and rent it to you monthly. We do all five, encrypt everything with XChaCha20-Poly1305 before it leaves your device, and charge once instead of forever. The encryption core is open core, published so the claims can be verified rather than trusted.

Adeux.app's answer

Most relationship apps focus on a single feature, like questions or date ideas. Adeux brings everything couples need into one simple and private space: communication, shared memories, fun interactions, and emotional connection tools. It’s also built with simplicity in mind, so couples can use it naturally in their daily lives without it feeling like work.

PrivacyNotes's answer:

Three reasons:

• One app, not four subscriptions. Standard Notes, Day One, and Lunatask each rent you a slice (notes, journaling, tasks). PrivacyNotes covers all of them plus files and a vault, for a fair one-time fee.
• Real zero-knowledge. Your keys come from a recovery phrase that never touches our servers, so we cannot read your notes, your filenames, or your metadata. Some encrypted apps leave note or task metadata in the clear; we do not.
• Verifiable, not just trusted. The crypto and schema are open core and published for review, and there is no ad, tracker, or analytics anywhere in the app.

Adeux.app's answer

Adeux is designed for couples who want to stay emotionally connected and create meaningful moments together. This includes long-distance couples, partners who want to communicate better, and people who enjoy documenting memories and growing their relationship intentionally.

PrivacyNotes's answer:

Privacy-conscious individuals and independent professionals who handle information they would not want a vendor reading: lawyers, journalists, healthcare and mental-health practitioners, developers, security specialists, researchers, and founders. It also fits anyone who simply wants one private home for their notes, tasks, journaling, and wellness tracking instead of spreading them across surveillance-funded apps.

Adeux.app's answer

Adeux was created by Can, a solo developer, for his fiancée Eva. During a difficult period in their lives when Eva had to undergo heart surgery, he wanted to create a private space where they could share memories, ask meaningful questions, and stay emotionally connected. What started as a personal project for their relationship eventually became an app available for couples around the world.

PrivacyNotes's answer:

PrivacyNotes started from a simple frustration: staying organized meant scattering your life across half a dozen apps, most of which could read everything you typed and billed you monthly for the privilege. We wanted one place for notes, tasks, journals, files, and passwords, encrypted so thoroughly that the people running the servers could not read a word of it, and paid for once rather than forever. So we built the encryption first, made the keys live only on your device, and published the crypto as open core so the promise could be checked, not just believed. Everything else grew from one rule: your data is yours, and no one else's to mine.

Adeux.app's answer

Adeux is built using modern mobile and backend technologies, including Swift for the iOS application, secure cloud infrastructure for data storage and synchronization, and encryption mechanisms to protect private conversations and memories.

PrivacyNotes's answer:

React, TypeScript, Vite and Tailwind CSS.

Adeux.app's answer

Adeux is primarily used by individual couples rather than large organizations. Some of the main user groups include:

Long-distance couples

Newly dating couples

Married couples

Couples who enjoy documenting memories together

Partners looking for tools to improve communication and connection

PrivacyNotes's answer:

Honestly? We have no idea, and that is the entire point. Signup is anonymous (a recovery phrase or Google, no email or personal details), the app ships zero analytics and zero trackers, and zero-knowledge encryption means we cannot see who you are or what you store. We could not name a single customer if we tried. A privacy product that tracked its users closely enough to brag about them would be missing the plot.
