Frequently asked questions

No. Birikimli is a tracking tool: it doesn't trade, hold money or access your brokerage or bank accounts. You enter your transactions yourself (by hand or from a CSV/Excel file) and we keep the prices up to date.

No. Nothing in the app is investment advice or a buy/sell recommendation. Investment advice can only be given by licensed institutions on a personal basis. See the Legal Notice (in Turkish) for details.

Turkish (BIST) stocks, US stocks and ETFs, Turkish mutual, pension (BES) and exchange-traded funds via TEFAS, crypto, foreign exchange, and gram gold and silver, all in one portfolio.

The web and mobile apps are available in English and Turkish: switch the language under Settings or with the language switch in the app. Emails, push notifications and PDF reports follow your language setting. Legal documents, the free calculators and the guides are currently in Turkish only.

Yes, iOS and Android apps use the same account as the web app, so every transaction you add on the web shows up on your phone.

With the average-cost method: buying fees are added to cost, selling fees are deducted from proceeds, and realized gains on partial sales are reported separately.

Each transaction is stored with that day's USD/TRY rate and gram-gold price, so your return in dollars or grams of gold uses historical rates rather than today's.

Every purchase, sale and dividend is carried to today's money using Turkish CPI (TurkStat) at its own date, and your current value is compared with that adjusted net investment. Months for which CPI hasn't been published yet are not estimated.

We do not provide tax calculation or filing services. The app estimates the withholding tax on dividends and interest using common rates to show net amounts, and the yearly statement lists realized gains and dividends in lira. These are informational estimates: exemptions, indexation, offsetting and your personal situation are not applied, and the statement is not a ready-to-file result. For filing, use official sources and a licensed accountant.

Free is enough to start tracking with one portfolio and up to 10 holdings. As your investments grow, Pro is the natural next step: 20 portfolios with up to 500 holdings each, 5-year history and benchmarks, risk analytics, rebalancing, dividend forecasts, shared portfolios and PDF tax reports are Pro-only. Yearly billing gives you 2 months free, and you can try Pro for free first.

Yes. Once you have started using the Free plan (you have entered transactions), you can try Pro once for 7 days without entering a card. When the trial ends the account returns to the Free plan automatically, nothing is charged and your data is kept.

Yes. If your first Pro payment is for the monthly plan, you get 10 extra days of Pro on top of the month you paid for, at no extra cost. It applies once per account, to the first payment only. One-off payments do not renew automatically.

It is your choice. A one-off payment covers the period you choose (monthly or yearly) and does not renew; when it ends you return to the Free plan, and you can extend whenever you like. If you pick the auto-renewing subscription, your card is charged the same amount every month or year (for yearly plans we email you 7 days before renewal). You can cancel at any time on the Subscription page: renewals stop and Pro stays active until the end of the period you paid for.

The first 500 auto-renewing subscriptions get a reduced price (TRY 99 a month or TRY 999 a year) that stays fixed for as long as you remain subscribed, for at least 24 months. The offer applies to auto-renewing subscriptions only; once the spots are gone or the offer ends, new subscriptions start at the regular price (TRY 149 a month or TRY 1,490 a year). While it is open you can see the remaining spots on the Subscription and Pricing pages.

Pro normally unlocks within seconds of payment; refresh the Subscription page. If it did not, email support from your account's email address with the payment date and amount. We will check the payment and, if the problem is on our side, unlock Pro manually or refund you.

Pro is a service performed instantly, so a period you have used is not refunded merely because you changed your mind; duplicate or incorrect charges, a membership that never opened, and charges taken despite cancellation are refunded. The Refund and Cancellation Policy page explains how to submit a request and the response time.

Payments are taken by a licensed payment provider using credit or debit cards. Your card details never reach Birikimli's servers.

Passwords are stored with bcrypt, sessions use secure HttpOnly cookies, and we never sell your data. Your portfolio and transactions are never shared with ad providers. The free plan shows ads (advertising cookies load only if you consent); Pro has no ads at all. You can turn on two-step verification (authenticator app or passkeys), download all your data as a ZIP, and delete your account and data at any time.

Yes, on the Pro plan: API keys (read-only or read-write), signed webhooks for alerts and transactions, and a one-formula connection to Google Sheets or Excel. See the API documentation page (in Turkish).
