Hujjatlar bo'limi yaratuvchilarga o'z fayllarini (PDF, doc, slayd, jadval va h.k.) ehtiyojmandlarga sotish imkonini beradi. Har bir hujjat uchun yaratuvchi muqova rasm, sarlavha, tavsif, bepul oldindan ko'rish (preview) fayli va to'liq fayl yuklaydi. Foydalanuvchilar to'lov amalga oshirgandan so'ng to'liq faylga ega bo'ladi.

Hujjat egasi (Document owner):

• Yuklangan har bir hujjatning yagona egasi va muallifi — uni yuklagan yaratuvchidir. Platforma hujjatga hech qanday mulkiy yoki mualliflik huquqlariga ega emas.
• Yaratuvchi platformaga hujjatni saqlash, ko'rsatish, sotish va yetkazib berish uchun nomutaqil (non-exclusive), royalti-siz, dunyo bo'yicha cheklangan ruxsat (litsenziya) beradi — bu litsenziya hujjat o'chirilganda yoki yaratuvchi hisobi yopilganda avtomatik bekor bo'ladi.
• Platforma hujjatni o'zining mahsulot yoki marketingi sifatida ishlatish, qayta sotish yoki uchinchi tomonga uzatish huquqiga ega emas — faqat sotuvni rasmiylashtirish va sotib oluvchiga yetkazib berishdan iborat texnik xizmat ko'rsatadi.

Yaratuvchining to'liq javobgarligi:

• Hujjat mazmuni, aniqligi, qonuniyligi, sifati va mualliflik huquqiga rioya qilinishi uchun faqat yaratuvchi javobgar.
• Yaratuvchi yuklagan hujjatga nisbatan zarur barcha huquq, ruxsat va litsenziyalarga ega ekanligini va uchinchi shaxsning huquqlarini buzmasligini kafolatlaydi.
• Boshqa shaxsning mualliflik huquqi, savdo belgisi, patenti, shaxsiy yoki maxfiy ma'lumoti, davlat siri yoki tijorat siri o'z ichiga olgan fayllarni yuklash qat'iyan taqiqlanadi.
• Noqonuniy, zo'ravonlikka chaqiruvchi, diskriminatsion, pornografik, ekstremistik, zararli dastur (malware) yoki firibgarlikka oid kontent yuklash taqiqlanadi.
• Hujjat hajmi 50 MB dan oshmasligi va ruxsat etilgan formatlardan birida (PDF, DOC(X), PPT(X), XLS(X), TXT, RTF, ODT/ODS/ODP, EPUB, ZIP/RAR/7Z) bo'lishi shart.
• Bepul versiya (preview) foydalanuvchiga hujjat haqida halol tasavvur berishi va to'liq versiya bilan mazmunan mos kelishi shart — chalg'ituvchi yoki firibgarlik preview taqiqlanadi.
• Sotib olingan hujjat tavsifda yozilgan natija va sifatga mos kelishi shart; aks holda yaratuvchi mijoz oldida shaxsan javobgar.

Platformaning roli va mas'uliyat chegarasi:

• Oson Test platformasi nashriyot, sotuvchi yoki muallif emas — yaratuvchi bilan sotib oluvchi o'rtasidagi sotuv shartnomasi nazaridan faqat texnik vositachi (saqlash, to'lov, yetkazib berish) hisoblanadi.
• Platforma hujjat mazmunini oldindan tekshirmaydi, tahrir qilmaydi yoki kafolatlamaydi. Sotib olishdan oldin bepul preview fayli va tavsifni diqqat bilan o'rganish foydalanuvchining mas'uliyatidir.
• Platforma hujjat ortida turgan ma'lumotning to'g'riligi, foydaliligi yoki maqsadga muvofiqligi uchun hech qanday kafolat bermaydi.

Shikoyatlar va kontentni o'chirish (takedown):

• Mualliflik huquqi yoki qonun buzilishi haqidagi shikoyatlarni aloqa bo'limi orqali yuborish mumkin. Asosli da'vo tushgan zahoti platforma hujjatni vaqtinchalik yoki butunlay o'chirish huquqiga ega.
• Qonun buzilishi yoki sud organlarining so'rovi bo'yicha platforma hujjat, yaratuvchi va sotib oluvchi haqidagi tegishli ma'lumotlarni vakolatli organlarga taqdim etishi mumkin.
• Takroriy yoki og'ir huquqbuzarlik holatida yaratuvchi hisobi ogohlantirmasdan bloklanishi va hujjat balansidagi mablag' tekshiruv tugaguniga qadar muzlatilishi mumkin.

Zararni qoplash (indemnification):

Yaratuvchi yuklagan hujjat tufayli platformaga, uning xodimlariga, hamkorlariga yoki uchinchi shaxslarga yetkazilgan barcha da'volar, sud xarajatlari, jarima va zararlarni qoplash majburiyati to'liq yaratuvchining zimmasiga yuklanadi. Platforma bunday da'volar bo'yicha yaratuvchiga regress (qaytarish) talabini qo'yish huquqini saqlaydi.

Moliyaviy shartlar:

• Foydalanuvchi to'lovi yaratuvchining hujjat balansiga to'planadi.
• Asosiy balansga o'tkazishda 20%, bonus balansga o'tkazishda 10% komissiya ushlanadi (imtihonlar bilan bir xil tarif).
• Pulni kartaga yechib olishda 5% soliq qo'shimcha ushlanadi.
• Bepul hujjatlar uchun to'lov amalga oshirilmaydi, lekin tarqatish, saqlash va javobgarlik shartlari saqlanadi.

The ability to take exams on different platforms depends on the exam's settings. The table below lists the platforms available in each case:

Proctoring (Monitoring Mode)

• Fullscreen mode: the user must stay in fullscreen mode throughout the exam. Leaving fullscreen automatically ends the exam with a score of 0
• Camera monitoring: the user's face is captured via camera every 5 minutes
• When proctoring is enabled, the exam can only be taken through the website. Telegram bot and group quiz are automatically disabled
• Taking the exam individually in the mobile app depends on the creator's settings

Paid Exams

• Paid exams can be taken individually via the website, Telegram bot and mobile app (subject to the creator's settings)
• Group play (Kahoot-style) is not available for paid exams
• The exam fee is deducted from the user's balance before the exam starts

Group play (Kahoot-style)

• Group play is only available for free exams with proctoring disabled

CEFR exams determine your level on the Council of Europe's language proficiency scale (A1 — C2) and consist of 4 skills: Listening, Reading, Writing, Speaking.

What data we store

• Answers submitted for each skill and the resulting percentage
• Your Writing essay is stored in full text form
• The audio recording you upload in the Speaking section is stored as a file
• The final CEFR level (A1, A2, B1, B2, C1 or C2) and the attempt timestamp

Who can see it

• You: your own result, per-skill score, list of your answers
• The exam creator: all participant answers submitted to their exam (including Writing text and Speaking audio) — needed for manual grading
• Administrators: for troubleshooting and investigating policy violations

IELTS exams consist of Listening, Reading, Writing and Speaking skills; results are reported on the band scale (0–9, in 0.5 increments). Both Academic and General Training types are supported.

What data we store

• Listening and Reading: selected options and text answers submitted per question
• Writing (Task 1 and Task 2): your text is stored in full and graded by a human (grader)
• Speaking (async mode): the audio recording you upload is stored as a file on the server (in the ielts/audio/ folder)
• Speaking (scheduled mode): the booked time and a live video call with the grader (the exam creator) — described in detail in the next section
• Band results: a 0–9 band per skill and an overall band (the average of the 4 skills, rounded to 0.5)

Proctoring (for IELTS)

• If the exam creator has enabled camera monitoring, a webcam snapshot is captured every minute and the system automatically checks for faces
• Snapshots and violation events (no face detected, or multiple faces detected) are stored and visible to the exam creator and administrators
• IELTS proctor snapshots are stored on the server in a separate folder (ielts/proctor_snapshots/) organized by date
• If fullscreen is required, the attempt is terminated automatically when you exit fullscreen

Human grading

• Writing and Speaking skills are graded by a human (usually the exam creator or a grader they have assigned)
• The final overall band is released only after Writing and Speaking have been graded
• The grader reads your full essay and listens to your audio recording. Their comments may appear on the result page

The scheduled IELTS Speaking mode connects you with the exam creator (grader) at the agreed time through a live video call. The call runs in your browser using WebRTC technology.

How it works — technical notes

• The video and audio stream is sent directly between your browser and the grader's browser (peer-to-peer). The server does not record or store these streams
• To establish the peer-to-peer connection, technical signaling messages (SDP, ICE candidates) are exchanged through a server-side cache — these messages are automatically deleted within 1 hour
• The call room opens 5 minutes before the scheduled start and closes 10 minutes after the scheduled end
• The platform does not yet run its own TURN server. Calls may fail for users behind restrictive NATs

What you share

• The video and audio stream from your camera and microphone — the grader sees and hears you. Access to the camera is only possible with explicit browser permission
• Text messages you send in the video room's chat panel — messages are kept in the server cache for 1 hour and then automatically deleted
• The call duration (the booked slot) and the call status (whether it took place or not)

Recording

• The platform does not automatically record the call or store it on the server
• The grader may record the call at their discretion — but must notify you in advance

The platform may not be used by persons under 14 years of age. Users aged 14-18 may use the platform with parental or legal guardian consent.

If we discover that we have collected data from a person under 14, such data will be immediately deleted.

We reserve the right to modify this privacy policy at any time. Significant changes will be announced on the platform.

Continued use of the platform after changes constitutes acceptance of the updated terms.
