Encrypted code-based chat. No phone. No email. No account. Share an 8-character code with someone. They type it in. You are talking. End-to-end encrypted from your device. Nothing to log in to. Nothing to back up. WHY NO TRACE WORKS • No phone number — no SMS confirmation that fails in your country. You install, you chat. • No email — no recovery flow you have to remember. • No account — no profile, no friend list, no directory. • 8-character code — share on paper, by voice, by QR. Whoever has the code joins. Whoever does not, never sees the room. • Optional 2-layer code — share a room without leaking access. The join-code is the second gate. • Three privacy presets — Ghost saves nothing on your phone, Balanced keeps codes for one-tap re-open, Comfort keeps history too. Change anytime. • Screen-recording lock — your chats render as black in screen recorders. • App lock — optional tap-code on every launch. • 1-tap delete all data — Settings > Account > Delete. Nothing kept on our side. HOW IT IS DIFFERENT Signal needs a phone number. Telegram needs a phone number. WhatsApp needs a phone number. Threema gives you a permanent ID that lives forever. No Trace gives you a throwaway 8-character code per room — no identity follows you. WHO PICKS IT • Journalists collecting tips • Lawyers and doctors with confidentiality duties • Activists and advocates • Two people who want a chat that does not sit in either phone's backup • Teams who want a side channel separate from work tools CROSS-DEVICE iPhone, iPad, Web, macOS, Linux. Open the room on whatever you have nearest. PRIVACY YOU CAN VERIFY • No ads • Tracking limited to crash + basic analytics, disclosed in our privacy policy • Premium uses Apple Pay only — no external payment links • Delete all your data anytime: Settings > Account > Delete CONTENT SAFETY We have zero tolerance for objectionable content and abusive users. Every message can be reported with one tap (long-press > Report) and is reviewed within 24 hours. You can block any sender locally on long-press. Senders flagged for objectionable content are removed and ejected. Contact: hello@teamzlab.com. FEATURES • 1:1 and small-group code-gated rooms • Featured Topics — public rooms with daily prompts • Reply-to threading + emoji reactions • Edit and delete your own messages • Report and block any sender • Long-press copy • QR share for in-person joins • Three privacy levels you control PRICING 50 free messages on install. Premium is a one-time purchase — lifetime unlimited messages. No subscriptions. No recurring charges. No renewal. Install No Trace. Create a room. Share the code. That is the whole onboarding.

تطبيق أثر (Athar) هو منصة اجتماعية مجهولة الهوية بالكامل، مصممة خصيصاً لتمنحك مساحة حرة ونقية للتعبير عما يجول بخاطرك من أفكار، أراء، خواطر، أو مشاعر دون قيود أو مخاوف من الأحكام الاجتماعية. لماذا أثر؟ مجهولية تامة ومطلقة: لا توجد أسماء مستخدمين، لا توجد صور شخصية، ولا ملفات تعريفية عامة. أنت تعبر بمجهولية تامة وعبر أسماء عشوائية يولدها لك التطبيق تلقائياً. عمر محدد للأثر (24 ساعة): كل منشور أو فكرة تشاركها تعيش لمدة 24 ساعة فقط، ثم تتلاشى وتختفي تماماً وتلقائياً من قاعدة البيانات، لتترك مساحة لأفكار جديدة وتجارب متجددة. نظام تفاعل نقي: تفاعل مع منشورات الآخرين عبر الإعجاب ، وعبر عن تقديرك للأفكار التي تلامس قلبك لتظهر في قائمة مفضلاتك الخاصة المحفوظة بأمان وتشفير كامل على جهازك. أثر ليس مجرد تطبيق، بل هو مساحة للتأمل، والبوح، وترك أثر طيب يمر بسلام ويرحل بهدوء.
