Press kit
No form. No email address required. No tracking of any kind on this page — every font and image on it is served from this domain, and there is not a single request to anyone else. Take what you need.
Before you write: Yesterself has not shipped yet. The target release date is 15 December 2026 on iPhone and Android. Everything below describes the product as it is being built and tested; where a number or a date could still move, this page says so rather than rounding it into a claim.
Questions, review builds, or anything at all: hello@khreshitech.solutions. One person answers, usually the same day.
The story, in one line
The journal that writes back — and can't read your diary.
Every journal ever built asks you to write into a void. Yesterself makes the void write back: each morning it delivers a small stack of letters assembled overnight on the device — last night's note, a time capsule you postmarked months ago for that exact date, an entry from that day in an earlier year, and one past letter surfaced because it echoes the week you are having. Each evening you reply for two minutes, and any sentence of that reply can be postmarked to a future date.
The architectural constraint that makes it interesting: retrieval over a whole archive and end-to-end encryption are mutually exclusive if the retrieval runs on a server. So none of it runs on a server. Speech-to-text, the resonance that finds the echo of one letter in another, the quarterly retrospective and the reading voice all run on the phone, in software shipped inside the app.
The three images
All three are real captures of the running app. None is a mockup, and none contains a real person's writing — every line shown was written for the capture.
Boilerplate, three lengths
Please use one of these verbatim. They exist so that coverage converges on the same sentences rather than on three different approximations of them.
Yesterself is a journal that writes back: every morning it delivers mail written by your past selves, with every AI feature running privately on the device.

Yesterself is a journal that writes back. Each morning it delivers mail from your past selves: last night's note, a time capsule you postmarked months ago for that exact date, an entry from that day in an earlier year, and one past letter surfaced because it echoes the week you are having. Each evening you write or speak a two-minute reply, and any sentence can be postmarked to a future date. Speech recognition, retrieval and retrospectives all run on the device; optional sync is end-to-end encrypted and the server's source is published. There are no streaks. Export is always free.
Fact sheet
| Name | Yesterself |
|---|---|
| One line | The journal that writes back — and can't read your diary. |
| Category | Lifestyle (secondary: Productivity) |
| Platforms | iPhone and iPad (iOS 17.0 and later); Android 10 (API 29) and later |
| Target release | 15 December 2026, both stores, English-first |
| Free plan | Unlimited written letters · three spoken letters a week · one time capsule in flight · morning mail and on-this-day · resonance across the last 90 days · full import · full export, forever · the Lantern widget. No account, no email address, no expiry. |
| Yesterself Post | $29.99 a year or $4.99 a month (US pricing; each store shows its own currency). Adds end-to-end encrypted sync, unlimited voice and capsules, retrieval across the whole archive, the quarterly Season of Selves, and the Annual Volume. |
| Trial | 21 days, everything included, no payment method collected at any point. On day 19 a notification names the date and the price. On day 21 you choose. Nothing is charged automatically, because nothing was ever on file. There is no weekly plan. |
| Founder Lifetime | $99 once, 500 exist, launch window only. The number shown on the paywall is the server's true remaining count, never a countdown and never invented; when it cannot be fetched the offer is hidden rather than guessed at. A further 50 lifetimes exist outside the 500 for creators, so gifting one never takes a place from a buyer. |
| Developer | One person. Yesterself is a Khreshi Tech product. |
| Contact | hello@khreshitech.solutions. One mailbox, read by the person who built the app. |
| Privacy policy | yesterself.khreshitech.solutions/privacy.html — published in advance, version 1.1, effective 14 December 2026 |
| Security disclosure | yesterself.khreshitech.solutions/disclosure.html |
| Server source | github.com/yesterself/yesterself-server — AGPL-3.0-or-later, with the protocol spec, test vectors and OpenAPI file under Apache-2.0 so an independent client is legally trivial to write. Public at launch. |
| Analytics | None. No SDK, no events, no crash reporter of ours, no attribution. This is a permanent non-goal, not a launch position. |
The five claims, and where a sceptic checks each one
Every sentence we will ever put in front of you is an instance of one of these. If a sentence does not serve one, it is decoration and it gets cut.
| Claim | The one-sentence proof | Where to check it |
|---|---|---|
| The journal writes back. | Morning mail is assembled overnight from your own archive: last night's note, a due capsule, on-this-day, and one resonant letter. | Images 01 and 02 above |
| It cannot read your diary. | The free tier transmits nothing at all; premium sync uploads ciphertext keyed to 12 words that never leave the phone. | The published server source; the privacy policy |
| The mail never goes silent — and there are no streaks. | A strict fallback ladder guarantees an envelope every morning; the only counter grows. | Image 01; the app has no streak anywhere in it |
| Your archive is never hostage. | Free Markdown, JSON and audio export, forever, two taps, offline; free import from Day One, Markdown and — best effort — Apple Journal. | Image 03; the published export format |
| Billing never surprises anyone. | 21 days free with no payment method collected; a day-19 notification that names the date and the price; one-tap cancel; no weekly plan. | The day-19 notification is itself a shareable artefact |
Fact-check sheet
The ten things that are easiest to get slightly wrong, each with the phrasing that is accurate. We would rather be corrected here than in a reader's comment.
| Not this | This |
|---|---|
| "AI-powered journaling app" | Every intelligent feature runs on the device, in software shipped inside the app. Nothing is sent anywhere to be processed, and there is no cloud model in the product. |
| "They promise not to read your journal" | Cannot, not "does not". Free-tier writing never leaves the phone at all; synced writing arrives as ciphertext keyed to a phrase the server never receives. |
| "Free trial — card required" | The 21-day trial collects no payment method at all. Nothing can be charged automatically because nothing is on file. |
| "Imports from Apple Journal" | Apple Journal export is a PDF. Recovery is best-effort text extraction, not a full import — dates and structure may be imperfect, and the app says so on the screen where you do it. Day One JSON and Markdown import fully. |
| "Free for 21 days, then you must pay" | The free plan is not time-limited. It is the whole daily ritual, forever. The trial is 21 days of the paid extras. |
| "Export is a premium feature" | Export is free on every plan, forever — Markdown files, one JSON, your original audio. No watermark, no quota, no cooldown. |
| "Keeps you honest with a streak" | There are no streaks anywhere in the product. There is one number and it only grows: the days of your life that are in here. |
| "Open-source journaling app" | The sync server is open source (AGPL-3.0-or-later), along with the protocol spec and test vectors (Apache-2.0). The client is not open source, and we say so plainly. |
| "Limited-time founder pricing" | Founder Lifetime is 500 places, launch window only, at a true count shown on the paywall. It is a cap, not a timer, and when the count cannot be fetched the offer is hidden rather than estimated. |
| "The team behind Yesterself" | One developer. Not a company with a team, and there is no funding round to ask about. |
