2doc reads the texts, calls and chats already on your Android phone and lays them out as a PDF: a document you can print, share or hand in. Nothing leaves the phone. A free SMS backup and restore is built in.

Pick a contact and a period, and the thread becomes a document: a date line for each day, the time on each message, your side and theirs, MMS photos where they were sent. It reads the phone's own message store, so it is complete for the period, not a pick of screenshots.
How it worksHow to printA WhatsApp chat goes in as the export WhatsApp itself makes, with or without its media. A Telegram chat comes in through your own Telegram account, any chat you can open. Both come out as the same kind of document, every speaker named.
WhatsApp guideTelegram guideThe call log becomes a table, one row per call, grouped by day, with the direction, the time and the duration, and a total for the period. Contacts become a printable directory of names, numbers and emails.
How it worksA document can hold several sections: messages from more than one source, calls, calendar events, images, device details, and a note saying what the document is. You order the sections and set each one's period.
The result is an ordinary PDF with page numbers on every page. Send it through Android's share sheet, print it through Android's print dialog, stamp a watermark on it, or share a copy that needs a password.
Backup writes your SMS, MMS and call log to an XML file on the phone, with a password if you want one. Restore puts them back on this phone or a new one and adds only what is missing. Free in full.
For a court, an official body, or an insurance or employment dispute. Screenshots show what was on the screen, mostly without dates, in whatever order they were taken. A 2doc document covers the whole period you choose, with the day and the time on every message, both sides of the conversation, and page numbers, so a gap shows. The guide to a complete record says what to add and what to check first: How to build a complete record.
For yourself. A conversation on paper. A chat saved before you leave the group. Your texts and calls carried to a new phone. An archive of your messages that is yours, outside any app.
2doc has no server and no account of its own. It reads your messages, calls and chats on the phone, and the document stays on the phone until you share it yourself; a backup file works the same way. Telegram chats come in through your own Telegram account. The one other network use is off until you turn it on: link previews, where the title and picture of a linked page come from that page's site.
The details are in the privacy policy.
Free, with no ads: a conversation or a call log for the shorter periods, a WhatsApp or Telegram chat, printing, and all of Backup & Restore. Pro is one purchase, once, with no subscription: the longer periods and custom dates, more than one conversation in a document, more image layouts, and no "Created with 2doc" line in the page footer.
